Study on a quasi-CW Nd:YAG frequency-doubled laser at 660nm
A QCW Nd:YAG intracavity frequency doubled red laser was made. Using a flat—flat laser cavity, 2 Kr-lamps, KTP crystal and an AO Q-switch, 2 W output power at 660 nm was obtained. The relationship between laser cavity length and output power is analyzed.
Nearly-Noncritical Phase Matching in MgO:LiNbO3 Optical Parametric Oscillators
We propose and demonstrate nearly-noncritical phase-matched optical parametric oscillation in MgO:LiNbO3 crystal by temperature tuning. The tuning range of the OPO was 800-1700 nm with temperatures tuning from 83°C to 224.2 °C.
Continuous automatic scanning picosecond optical parametic source using MgO.LiNbO3 in the 700-2200 nm
A ps automatic tuning parametric Nd:YAG laser based on a single pair of MgO.LiNbO3 crystals is described. Energy and power efficiencies obtained are 5.4 and 8.6 percent, respectively. In a wide wavelength range, a single pulse of less than 30 ps is observed with bandwidths of approximately 1 nm and a peak power over 1 MW.
