Abstract

Triangular slabs made of Nd:YAG or Nd:YAP crystals were tested as active media for diode-pumped lasers. The resonator arrangements for the Q-switched regime were prepared for emission corresponding to the Nd³⁺ ion transition ⁴F_3/2→⁴I_13/2in each crystal (λ=1318 nm for Nd:YAG, and λ=1342 nm for Nd:YAP). Optical pumping was accomplished by a fast-axis collimated quasi-cw diode laser stack with peak power of 600 W delivering up to 150 mJ of pump energy. In free-running regime, the maximum reached energies were 24 and 27.5 mJ for Nd:YAG and Nd:YAP crystals, respectively. The corresponding slope efficiencies were 19.9% and 23.7% for Nd:YAG and Nd:YAP laser oscillators, respectively. The passive Q switching for 1.3-μm wavelength was accomplished by means of a saturable absorber made of V³⁺:YAG crystal, whose initial transmission was optimized for the shortest possible pulse length. The 6-ns-duration giant pulses were obtained with energies of 740 and 432 μJ for Nd:YAG and Nd:YAP, respectively. These results correspond to attained peak powers of 125 kW (Nd:YAG) and 77 kW (Nd:YAP) in the fundamental TEM₀₀ mode, which allows this laser to be used as an efficient source for further nonlinear conversion or other applications.
