Frequency-doubled solid-state lasers.

摘要

A doubled-frequency solid-state laser with folded resonator and end pumping by laser diodes (211, 212, 221, 222) from both ends. The deflection and output mirror (5) is additionally anti-reflection-coated for the pumping light at both ends. …??Using four laser diodes (211, 212, 221, 222) of 3 Watt light power each, 1.5 W output power at 532 nm is achieved with ND:YAG (1) and KTP (4). …??Two laser diodes (211, 212; 221, 222) each on each side of the laser rod (1) are preferably combined via polarising beam dividers (218, 228). …??The deflection angle is 10 DEG to 60 DEG , typically 50 DEG . …IMAGE…
