| Abstract: | YAG: Nd lasers with transverse diode pumping of a cylindrical active (lasing) element are developed and studied. Pumping is
carried out with continuous-wave (cw) laser diode array modules. At pump powers of 500, 820, and 1400 W, the output powers
of the lasers operating in the multimodal regime are, respectively, 150, 350, and 500 W. The optical efficiency exceeds 30%.
In the case of an unstable resonator operating in the negative branch of the stability diagram, the laser power equals 320
W with a beam divergence only twice as large as the diffraction limit. The design of a YAG: Nd laser pumped with pulsed-periodic
laser diode array modules is presented. The total pump energy is 5 J, and the width and repetition rate of pulses are, respectively,
250 μs and 100 Hz. |
