12W UV laser based on Air-cooled Double-end-pumped Intra-cavity

Abstract

12W UV laser generator is developed as a second harmonic generator and a third harmonic generator, in which a folded resonance cavity is composed of two laser diode side-pumped Nd:YAG modules, an electro-optic Q-switch, two LBO crystals. The air-cooled double-end-pumped Intra-cavity is studied and designed, the laser wavelength is 355nm, its maximum output power is 12.34W at repetition rate of 15kHz.The corresponding pulse width is 12ns. And the optical-optical efficiency of the fundamental laser is about 41%.
