Abstract
A laser with high average power, high repetition rate, ultra-short pulsewidth, and excellent beam quality is described. This is achieved by the use of high power diodes used to uniformly pump an improved Nd:YAlO.sub.3 crystal, resulting in a beam with excellent quality. In addition, a beta-barium borate (BBO) crystal, used in conjunction with drift step recovery diodes (DSRDs), forms a high speed optical switch which can be used to cavity dump the laser.
