Master Oscillator
Master oscillator is a module of rigid design mounted on invar rods to ensure mechanical and thermal stability. Oscillators cavity is formed by high reflectivity mirror and an uncoated glass Fabry- Perrot etalon used for the longitudinal mode selection. Part of the electro-optical Q-switch between electrodes is used as classical Q-switch, while another part together with the polarizer and PIN photodetector are forming negative feedback system (NF system). This negative feedback is used for selection of SLM lasing. When lasing appears, part of light reflected by polarizer hits PIN photodetector. Voltage generated by the FBC electronics and applied to the electrode is proportional to the light intensity registered by the PIN photodetector. In result the NF system allows master oscillator to keep lasing at certain low level for prolonged Oscillator contains aperture for the single transversal mode time (several tens of microseconds). During this time SLM (single selection. Quarter wave plates prevents the interference frequency) is establishing due to the selective properties of Fabry- and hole burning effects in the active element. Master Perot etalon and lower gain for the other frequencies. YAG:Cr oscillators output pulse is ~ 2.5 ns duration and its energy crystal improves SLM selection. is about 5 mJ. The pulse energy is monitored by pre- Laser control unit measures duration from the beginning of free calibrated photodiode and displayed on the remote control running to Q-switch opening moment and adjusts FBC electronics pad. to keep necessary value of that duration.
Compression System
Pulse compressor consists of optical guiding system and SBS-
cell with CCl4 liquid. SBS cell is designed for safe and longlife maintenance free operation. A linearly polarized light pulse from master oscillator passes through QWP and is focused into SBS-cell by lens. Focusing is arranged in the way to compress the pulse via SBS process. The backscattered Stokes pulse, as its phase is reversed, strictly repeats the path of pump pulse in the opposite direction and with a reversal divergence. The compressed pulse is guided into the amplification stage using polarizer and mirror. Amplification System
SL312 model lasers use multi-pass amplifier system which is based on laser chamber containing Nd:YAG rod pumped by two flash lamps. For smooth obtaining output beam profile pre- amplifier and double-pass amplifier layout is used in SL300 series SL300 Series lasers. Power amplifier includes optical components arranging passes through the active element. Aperture is employed to prevent the returning depolarized radiation from getting back into the SL312 model laser SL330/SL350 models lasers amplifier. Beam profiles (modulation on the near fields image are caused by CCD camera imperfection)
Harmonics Generation
The Nd:YAG laser fundamental wavelength can be frequency doubled, tripled and quadrupled inserting into the beam pass the nonlinear crystals generating corresponding harmonics. Harmonics generators, based on angle-tuned KD*P and KDP crystals, mounted in temperature-controlled heaters and harmonic separation optics, are available as standard options. The fundamental and harmonics pulses are separated by dichroic mirrors and each wavelength has a separate output port.
