Impact Statement:
Pulsed laser radiation at 1002 nm was generated at repetition rate of 3.7 kHz, with pulse energy of 0.23 mJ and duration of 5.5 ns, from a miniature Yb:LuPO4 crystal rod laser passively Q-switched by a GaAs semiconductor saturable absorber, with a quantum defect of 2.6%, the lowest among Q-switched Yb lasers pumped by 976-nm diode.
Abstract:
Low-quantum-defect pulsed oscillation at 1002 nm was achieved with a Yb:LuPO4 miniature crystal rod laser longitudinally pumped by a 976-nm diode laser, with a GaAs semiconductor saturable absorber to induce passive Q-switching. With 17.2 W of pump power absorbed in the crystal rod, an average output power of 0.85 W was generated at a repetition rate of 3.7 kHz, the resulting pulse energy, duration, and peak power were 230 μJ, 5.5 ns, and 41.8 kW, respectively.
