Abstract

Diagnostics of the plasma electron component by the method of Thomson scattering Te(R,t) of laser radiation makes it possible to reliably measure the spatial distributions of the electron temperature and density. One of the obstacles to the implementation of TS diagnostics in thermonuclear reactors is the distortion of the spectral characteristics of the optical system due to radiation-induced absorption and contamination of optical elements with erosion products of the first wall. As a consequence, the reliability of measurements by the TS method will decrease over time. The paper describes the method of multi-laser Thomson scattering, which will solve this problem. The results of the first experiments on the Globus-M2 tokamak are also presented. Keywords: plasma diagnostic, tokamak, thomson scattering, laser diagnostic, spectroscopy.

11. 10??W-level sub-100??ps 1??MHz MOPA laser with a microchip master oscillator

Author

Koval, V. V., Balmashnov, R. V., Pokrovskiy, V. P., Viktorov, E. A., and Kornev, A. F.

Abstract

A 10 W level master oscillator power amplifier (MOPA) laser with pulse repetition rate up to 1 MHz and 75–95 ps pulse duration was developed based on a passively Q-switched Nd:YVO_4 microchip 1064 nm laser as a master oscillator. A double-rod double-end-pumping configuration of two-pass Nd:YAG ring power amplifier was used to achieve high gain, near-Fourier-transform-limited pulses, and laser beam quality factor M^2=1.27 along both the horizontal and vertical directions.

Abstract

The authors describe a diode-pumped Nd:YAG laser that produces 920 mJ output energy pulses with a pulse duration of 76 ps at 200 Hz pulse repetition rate. Second-harmonic generation with a pulse energy of 730 mJ and pulse duration of 63 ps was obtained by using LiB3O5 crystal with II-type phase matching. The output beam divergence was about 1.5 × DL (the diffraction limit) and 1.9 × DL for 1064 and 532 nm wavelengths, respectively. [ABSTRACT FROM AUTHOR]

Abstract

Regenerative amplification of 946 nm pulses which are sliced from 12 mW continuous wave laser diode is reported. Near-transform-limited 2.9 ns pulses with highly stable and smooth temporal shape were obtained with the energy of 25 mJ/50 Hz and M² <1.2. [ABSTRACT FROM AUTHOR]

31. 8 ns Ho:YLF 3 micron laser

Author

Kornev, A. F., Nikitichev, A. A., Pokrovskiy, V. P., Leonid Soms, and Stoupnikov, V. K.

Abstract

Short pulse 3 µm laser is promising for medical applications, remote sensing techniques, and as the pump source for OPO operating in 5 µm spectral range. Unfortunately, low gain on the working transition of the most common diode pumped Er: YLF laser makes it difficult to obtain short pulses using Q-modulation techniques.
