Summary form only given. We propose and theoretically investigate an alternative approach to Kerr-lens mode-locking (KLM), which avoids the group velocity dispersion (GVD) compensation by use of a negative net nonlinear refractive index per cavity round trip. For the compensation of the positive nonlinear refractive index of the laser crystal we propose to utilize a nonresonant bulk semiconductor inserted in the tightly focused resonator section.

Summary form only given. In this paper, we investigate the effect of roughness on the reflectivity of laser facets. Given that mask pixel size is one of the possible sources of roughness and that high-resolution e-beam mask fabrication is costly, it is important to find the mask resolution required so that the fabricated laser performance is not significantly affected. To assess the importance of the roughness on the performance of our modeled devices, we calculate the light versus current (LI) characteristics, the coupling to higher order modes and the far-field patterns of etched-facet laser diodes with varying roughness.

Summary form only given. High-average-power 310-fs pulses were obtained with an all-fiber chirped pulse amplification (CPA) system. Both the oscillator and the power amplifier are based on Er/Yb-doped fiber for cladding-pumping with broad-area laser diodes. A single 10-cm-long fiber grating is employed in the CPA system as a compact femtosecond-pulse stretcher/compressor.

Summary form only given. We demonstrate for the first time that high-power and high-repetition-rate femtosecond fiber lasers can be constructed that require only simple broad-area diode-array pump lasers. To allow pumping with diode arrays, the standard single-mode erbium fiber of conventional oscillator designs is replaced with double-clad erbium/ytterbium fiber. Reliable femtosecond pulse operation is ensured by exploiting nonlinear polarization evolution for steady-state pulse shaping in environmentally stable cavity. Furthermore the use of chirped Bragg gratings allows the extension of the operation range of these types of laser into the picosecond regime.

Summary form only given. We generalized the theory behind the light-induced grating (LIG) electro-motive force (EMF) technique for material characterization and interferometry, first introduced by Petrov et al. In particular, we have accounted for the screening length, that allowed us to describe adequately the dependence of the amplitude, and the decay-time.

Summary form only given. The relatively weak attenuation of diffuse light as compared to ballistic light makes its use attractive for medical and biological imaging. A number of techniques have been developed to exploit diffuse light in imaging. These include imaging with diffuse photon density waves and the reconstruction from time-resolved transmission measurements. We have attempted to utilize acousto-optic modulation of diffuse light for imaging. We point out the consequences of the incoherent nature of the signal for tomographic imaging and demonstrate imaging of absorbing structures embedded within a strongly scattering medium with a resolution of approximately 2 mm. The sample that is excited by an ultrasound beam is illuminated by a laser beam.
