Abstract

A compact, passively Q-switched and mode-locked Nd:YAP laser in oscillator-amplifier configuration was designed and constructed. Operation wavelength switching (between 1.34 and 1.08 μm) was achieved with a three-mirror cavity and mechanical shutter. For Q switching and mode locking of the 1.34-μm Nd:YAP laser transition, a V³⁺-doped yttrium aluminum garnet (YAG) saturable absorber was employed. The optimal performance was found after variation of the resonator length (40 to 100 cm) and of the absorber initial transmission (52% to 89%). The duration of a single pulse in a train was around 1 ns. The saturation intensity of the V³⁺:YAG absorber was determined to be 10 MW/cm². A BDN II polymer thin-film saturable absorber was used for Q switching the 1.08-μm laser transition. After amplification, the maximum output energy reached was 27 mJ (train of mode-locked pulses at 1.34 μm) or 94 mJ (Q-switched pulse at 1.08 μm). The output laser radiation was delivered by means of a hollow glass waveguide coated with cyclic olefin polymer and Ag, with 95% and 80% efficiencies for 1.34 and 1.08 μm, respectively.
