We developed a 0.4 J diode-pumped 1064 nm Nd:YAG MOPA laser with pulse duration of 35 ps. The master oscillator was based on laser scheme with regenerative amplification of DFB laser diode radiation. The two-pass two-stage power amplifier was built o

We demonstrate a diode-pumped master oscillator power amplifier Nd:YAG 1064 nm laser with sub-joule-level output energy of 0.43 J, high pulse repetition rate of 200 Hz, and short pulse duration of 100 ps. The 5 mJ master oscillator consisted of a 100

We used a quadrant photodiode as a sensor of wavefront curvature in the compensator of thermally induced lens and wedge in laser rods. Sensitivity of the wavefrontcurvature analyzer λ/100 was achieved. Using of thermal lens compensator with such sen

A contradiction between high efficiency of an amplifier operating in a saturated mode, and nonlinear distortions in image reproduction characteristic for this regime is solved. A lasing medium is located in a Fourier-plane of the image, its gain prof

The present paper describes an alternative approach to the image forming, which is in a spatial modulation of the gain in the active medium, by the spatial modulation of the density of pump. The problems for the super-Rayleigh resolution are discusse

This article presents a choice of components for creating an effective pumping system for a YAG:Nd laser with a single-pulse energy of 60 mJ. An original design is proposed for the amplifier’s pump system. The efficiency of three types of illuminat

To obtain images, pump radiation is projected onto a thin layer of laser medium through a spatial light modulator. The lasing conditions for such a laser are analyzed, and it is shown that it is possible to generate gray-scale images.
