Amplified spontaneous emission (ASE) occurs in media with large gain, and affects both the magnitude and the spatial distribution of the inversion. In this work we theoretically study the effect of ASE in three-dimensional, rectangular slab amplifier

Heat generation and laser performance of Nd:YAG oscillators pumped in two regimes, band pumping at /spl sim/808 nm and "thermally boosted" (TB) pumping at 884.5 nm, are compared. The crystal, pumped with a Ti:sapphire laser, lased with slope efficien

We have demonstrated the feasibility of cooling high-power solid-state lasers with diamond windows, whose thermal conductivity is about two orders of magnitude higher than that of sapphire. An output power of 200 W was achieved from a single Nd:YVO/s

Direct pumping from thermally excited ground levels directly to the upper lasing level of Nd:YAG was demonstrated using high-power, 885 nm, CW diodes. 14 W output power with 0.63 slope efficiency and 0.53 light-to-light efficiency were obtained.

A Q-switched diode side-pumped Nd:YAG rod laser is presented. The design is based on close coupled diodes which are mounted side by side to a laser rod cut at Brewster angle. No intra-cavity optics are needed to compensate for the induced thermal len

The present paper is the first of a series reporting on a comprehensive study of the hydrodynamics, kinetics, and spectroscopy of the transient species formed following the detonation of lead azide (LA). The spatial and temporal behavior of the deton
