Xenon flash lamp pumped self-frequency doubling NYAB pulsed laser

Abstract

Neodymium doped yttrium aluminum borate (NYAB) crystals with sizes up to 45mm have been grown successfully. NYAB rod of φ4 × 12mm was pumped by xenon flash lamp, and several mJ of 0.53μm green laser output was obtained. The oscillation threshold, the pulse duration, the laser beam polarization, and the laser beam divergence were measured to be 78mJ, 100ns, 90% and 2mrad, respectively.
