Mercury1 is an advanced diode pumped laser facility under development at Lawrence Livermore National Laboratory as a 10% scale prototype of a single beamlet of a future inertial confinement fusion driver. The goals of this Yb:S-FAP based laser are 1 kW average power (100 J/pulse, 10 Hz) with a pulsewidth near 10 ns and a 10% wall-plug efficiency. High conversion efficiency (>50%) to the second harmonic (523.5) at the full aperture (3 cm x 5 cm) of the source is desired. We compare the potential of the available frequency conversion materials in the context of the peak and average power constraints using the ‘threshold power’ and ‘thermally limited power’ models developed at LLNL.

The second harmonic of Nd:YAG laser with short output wavelengths is interesting for applications in optical data storage and laser-printer technology. High repetition rate green laser source also can be used to high speed scanning imaging and pumping tunable laser. Intracavity doubling in diode-pumped solid state lasers seem to be a promising approach for frequency doubling. One advantage with this configuration is that the difficulties with the narrow acceptance bandwidth of the nonlinear material can be half than in external frequency doubling.

Although historically, organic materials have not been thought of as optical materials, organics are experiencing increased use as both passive and active optical components. Applications range from passive elements such as gratings, fibers, interconnects, lens, and prisms to active components such as light emitting diodes, electro-optic modulators, solid-state lasers, frequency doublers, optical memories, and sensor protection elements. The utilization of organic materials has typically involved competition with established technology based on inorganic materials. For example, polymeric optical fibers must compete with established silica fiber technology, polymeric electro-optic modulators must compete with established lithium niobate technology, organic light emitting diodes with a host of inorganic light emitting materials, etc. Unless organics offer special advantages, they have little chance of market penetration. A frequently quoted putative general advantage of organics, and particularly polymeric materials, is their processibility and low cost. In areas such as discrete passive components, this advantage clearly comes into play and has resulted with wide commercial use. Indeed, inorganic materials such as sol-gel glasses have major difficulty in competing with polymeric materials in the manufacture of passive discrete optical components. For applications, such as electro-optic modulators and light emitting diodes, the success of organics depends on a number of properties other than materials cost or processibility although even here processibility can be an important consideration for issues such as integration with semiconductor VLSI electronics.

The recently developed Raman excitation plus laser-induced electronic fluorescence (RELIEF) method of tagging oxygen molecules provides a powerful tool for studying turbulent structure in high-speed air flows. The advantage comparing with other flow diagnosis methods is that a nonintrusive, instantaneous structure of high-sped flow can be obtained by this new technique. For this method, it is necessary to pump oxygen molecules up to vibrational exciting states by two simultaneously pulsed high-power lasers whose frequencies differ by the vibrational frequency of oxygen(1555cm-1). The wavelengths of the two lasers are 532nm and 580nm, respectively, which are usually chosen as pump source for tagging oxygen molecules. In our experiment, nonlinear optical frequency conversion technology has been applied to generate 580nm coherent radiation.

A high power pulsed Nd:YAG laser were successfully designed , it includes three big YAG rods (ϕ10 × 150mm), six Krypton lambs and six power supplies with different pulse width and rise times .Here we use Krypton lamb instead of Xenon lamb because it has better spectrum match feature , high conversion efficiency and suited to long pulse operation. The power supplies have resonant and switched types(VDMOS and IGBT). Cooling system has internal and external circular systems. Whole system has a laser light fiber delivery device which can be transmitted high energy. Table shows the light shapes of Krypton lamp and shapes of laser pulses.

Recently, lasers operating in the eye-safe wavelength around 1.5 μm have found increasing demand in the laser radar (LIDAR). Raman laser pumped by well established lasers such as Nd:YAG lasers is a favorable candidate with such characteristics at high repetition rate, narrow linewidth, and good beam quality.1 As the Raman conversion medium, a Ba(NO3)2 crystal has attracted much attention because of its high gain and strong mechanical properties.2 Laser output in the eye-safe wavelength region can be obtained with the Ba(NO3)2 crystal either in a first Stokes line pumped by 1.3 μm Nd:YAG laser2, or in a third Stokes line pumped by 1.06 μm Nd:YAG laser3. When the Raman crystal exhibits substantial residual absorption in the pump or Stokes wavelength, these solid-state Raman lasers require some thermal management to scale up to high average power systems such as in LIDAR. Hence, we experimentally studied the thermal characteristics of the Ba(NO3)2 cascade Raman conversion process.

Photorefractive spatial solitons [1-3] are promising for applications in all-optical switching, optical interconnects and the development of novel photonic devices. We report on study of steady-state dark photorefractive screening-solitons, formed when a laser beam containing a dark notch propagates through a bulk strontium barium niobate crystal biased by an electric field. A dark photorefractive soliton, although generated with a weak beam, induces a waveguide in the bulk of the crystal that guides other strong beams of longer wavelengths. Fundamental, Y-Junction and multiple dark photorefractive solitons are observed, so are the waveguides they induce that can guide other beams into multiple channels [3]. A dark photorefractive soliton can also couple with another dark or bright soliton, forming interesting coupled spatial soliton pairs that consist of self-guided propagation of two beams in the photorefractive materials [4]. Recently, we have demonstrated steady-state self-trapping of circular and elliptical optical vortices (in both transverse dimensions) due to two distinctly different nonlinear mechanisms: the bulk photovoltaic effect in an unbiased LiNbO3 crystal, and the photorefractive screening effect in a biased SBN crystal [5].

The retracing behaviors of phase-matching angle, which are the key phenomena for realizing multiple-wavelength optical parametric oscillators (MWOPO), have been observed in a LBO crystal [1] and also studied in other crystals in the collinear phase-matching configurations. However, based on collinear phase-matching the implementation of MWOPO is limited by the specific ranges of pump wavelength, particularly for the widely used BBO crystal. In this paper, we, on the one hand, present the results of theoretical study on the retracing behaviors of a BBO crystal based on non-collinear phase-matching configurations. On the other hand, we demonstrate our experimental results of the retracing behavior of a BBO optical parametric oscillator (OPO) pumped by the second-harmonic of a Q-switched Nd:YAG laser. Particularly, we discovered that near the turning point of the retracing curve, there was an angle around which a broad wavelength range could be simultaneously phase-matched. Based on this observation, we have implemented an OPO with an extremely broad signal and idler spectra.

Optical paranetic oscillators (OPO) are attractive sources of coherent radiation in application for which laser sources are unavailable or for which wide tunability is needed. For samples, they can be used as mid-IR. countermeasure sources in military applications and can be applied into difference absorption lidar operating in the range of 2 ~ 14 μ m to monitor environment, medical diagnosis and treatment, material processing, scientific instrument, optical communication, low-light imaging, atmospheric aberration for astronomy and satellite tracing, optical signals processing, communication and imaging in water, remote sensing and identification biological materials. Many nonlinear frequency-conversion crystals such as lib3O5(LBO), KTiOPO4(KTP), β-BaB2O4 have been used in OPO devices. KTP is one of the best nonlinear frequency-conversion crystals, and it has high nonlinear coefficient, high damage threshold, easily-polished surface, and a broad transparency range[1,2]. So, Here, we focus our interest to KTP OPO.
