Description/Abstract

Diode-pumped Nd:YAG lasers operating at ~946nm are potentially attractive sources since they can be frequency-doubled to the blue. However, efficient lasing on the 946nm transition is considerably more difficult to achieve than on the more familiar 1.064µm transition. This is partly due to its quasi-three-level nature which results in a significant reabsorption loss which (at room temperature) is ~0.8%/mm for a 1% Nd doped YAG rod. The main problem however, with the 946nm line, is its small stimulated emission cross-section which is ~9 times smaller than for the 1.064µm line. As a result, 946nm Nd:YAG lasers have a threshold which is at least a factor of 9 times higher than for a comparable 1.064µm laser.
