A fast single-component objective with a corrector has been developed for focusing laser light down to a diffraction-limited spot. It has an aperture ratio of 1:1.61. For the first time, a method involving sintering and hot molding of glasses has been used to produce an aspherical corrector that can cancel a wave aberration of 352 wavelengths.

Single crystals of gadolinium vanadate doped with neodymium ions have been grown by the Czochralski method. The absorption and luminescence spectra of the neodymium have been measured. The absorption near 0.8 μm is higher than 70 cm−1. The lifetime of the neodymium ions is 90 μs. Laser action has been achieved on the transitions 4F3/2 → 4I13/2, 4I11/2. The differential efficiency of the lasing near 1.06 μm is 54%.

This review examines some questions concerning the capabilities of interference and polarization-interference correlation diagnostics of the amplitude-phase characteristics of random optical fields for the purpose of identifying these fields and then studying the corresponding objects. The diagnostics of random phase objects is discussed separately in the cases in which the phase dispersion of the inhomogeneities is less than and greater than one. The outlook is promising for the use of the correlation dimensionality of chaos in a field as a diagnostic parameter. It is also shown that the use of interference principles for a parallel processing of large data files can substantially increase the speed of processing systems.

When IR laser radiation that is intensity-modulated at a frequency of 1.1 GHz is incident on a conducting target in a rarified gas at a pressure of 0.1 torr, microwave modulation of the current pulses generated in the erosion plasma is observed. A microwave signal with a voltage amplitude of 2 V is obtained at a laser intensity of 100 GW/cm2. The efficiency of the conversion of laser energy to the microwave band at an intensity of 10 GW/cm2 is 2.5 ? 10?7.

The anomalous emission (λ~146 nm) from a Kr–Xe mixture observed in a previous study is interpreted as emission in the course of optical collisions. A kinematic model is constructed which explains the dependence of the emission intensity on the composition and temperature of the gas mixture.

It is predicted theoretically that the efficiency of self-mode locking can be raised by means of a bleachable shutter in the main cavity or an auxiliary cavity. The laser emits a stable train of ultrashort pulses under these conditions. The theory is based on a fluctuation model of the operation of a cw solid-state laser with a linear auxiliary cavity. The increase in efficiency involves a broadening of the region of parameter values of the system in which self-mode locking occurs, a significant decrease in the threshold pump intensity, and a reduced sensitivity of the operation to the phase mismatch of the lengths of the cavities. It is shown, for the first time, that a stable train of double ultrashort pulses can be generated by a system with a shutter in the auxiliary cavity. It is also shown that a self-mode locking is possible in the case in which there is a phase mismatch of the cavity lengths and there is no phase self-modulation in the main cavity.
