Generation of Pulsed Laser Radiation at 1002 nm with a Quantum Defect of 2.6%

Generation of Pulsed Laser Radiation at 1002 nm with a Quantum Defect of 2.6%

Low-quantum-defect pulsed oscillation at 1002 nm was achieved with a Yb:LuPO<sub>4</sub> 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 crysta...

Description
Summary:Low-quantum-defect pulsed oscillation at 1002 nm was achieved with a Yb:LuPO<sub>4</sub> 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&#x00A0;&#x03BC;J, 5.5 ns, and 41.8 kW, respectively.
