Generation of 7.8 W at 355 nm from an efficient and compact intracavity frequency-tripled Nd:YAG laser
چکیده انگلیسی

A high power, quasi-continuous wave ultraviolet laser at 355 nm was obtained by intracavity frequency tripling of a diode side-pumped acousto-optic (AO) Q-switched Nd:YAG laser. Type II critical phase-matched KTP and LBO crystals were used for the second harmonic generation and the third harmonic generation, respectively. Under the pump power of 180 W, 7.8 W average output power at 355 nm was obtained at 8 kHz with the pulse width of 50 ns, corresponding to the pump-to-ultraviolet conversion efficiency of 4.3%. The peak power and single pulse energies were estimated to be 18.8 kW and 938 μJ. Its far-field divergence was measured to be about 3.8 mrad. The instability of the 355 nm laser was less than 1% at an output power of 6.3 W for 2 h operation.
