“…As known hydrogen additives lead not only to a great increase in laser power but the laser beam profile pattern changes from annular to top-hat and Gaussian-like (Astadjov et al 1988). The influence of light polarization on M 2 was investigated within MOPA2 experiments.…”

The beam propagation factor, M 2 of the master-oscillator power-amplifier (MOPA) CuBr laser emission compliant with ISO 11146 is studied methodically. Statistical parameters of 2D intensity profile of the near and far fields of MOPA laser radiation are measured by a beam analyzing technique as functions of timing delay between MO and PA. For first time the influence of the gas buffer (causing the radiation profile to change from annular to top-hat and Gaussian-like) and light polarization on CuBr laser beam focusability (M 2 ) was under investigation. The MOPA gain curve is found and the influence of gain on the input signal (from MO into PA) due to the absorption/amplification in PA on the field profiles is shown. For annular radiation M 2 range is from 13-14 (small delays) to 5-6 (large delays) and for filled-center radiation M 2 is 6-7 (small delays) and at the end of gain curve is as much as 4. With polarized light, M 2 drops to 3 at the end of gain curve. The brightness of laser emission with hydrogen goes up 3-5 times and the linearly-polarized beam is at least 40% brighter than that of partial or non-polarized beams.

“…It was found that hydrogen changes the decay rates and the radial distribution of copper metastables in CBVL [5]. The reported studies on the effect of addition of hydrogen to neon buffer gas of the CBVL have highlighted the increase of total output power of the laser [1][2][3][4][5][6][7] however its effect on the spectral components of the output is not reported so far. The power and temporal characteristics of each spectral component of the laser are important in many applications, like sum frequency generation, dye laser pumping, etc.…”
