We report on a thin-disk Yb:YAG laser made from a Q-switched oscillator and a multipass amplifier delivering pulses of 48 mJ at 1030 nm. The peculiar requirements for this laser are the short delay time (< 500 ns) between electronic trigger and optical output pulse and the time randomness with which these triggers occur (with trigger to next trigger delay ges 1.5 ms). Details concerning the oscillator...
Lasers based on stimulated Raman scattering (SRS) of light in crystals (Raman lasers) are promising sources of radiation in wide spectral region. Using such lasers, an efficient quasi-continuous wave (quasi-CW) laser system generating multi-wavelength radiation is developed. Laser system is based on a quasi-CW nanosecond lamp-pumped Nd:YAG laser with acousto-optic Q-switching, Raman lasers on barium...
The effect of Nd3+ concentration on the CW and Q-switched laser performances at 1064 nm from Nd: YVO4 has been studied under diode laser pumping in identical laser configuration. The Nd3+ concentrations used were 1, 2 and 3 at.% in YVO4 crystals. Under the CW operations we have compared the thermal lensing effect, slope efficiencies and also the beam quality at the fourth-order degeneracy configuration...
