Paper Abstract

The influence of active media parameters on generation characteristic of microlasers is reported. Absorption bands of several laser crystals have been examined and the results are presented. Generation characteristics of the examined Nd:YAG, Nd:GGG, Nd:LSB and Nd:GLS microlasers with their single- frequency generation ranges are presented. The highest differential efficiency of 56% was obtained in Nd:YAG microlaser with 1 mm resonator length. The highest cw output power of a single TEM00 mode equal to 60 mW was reached in Nd:YAG microlaser with 0.8 mm resonator. The lowest threshold of generation was formed for Nd:GGG microlaser. Continuous frequency tunability of the Nd:YAG laser within the range of 103 GHz and with sensitivity equal to 3.1 GHz/K was shown. The relationship between experimentally measured range of generation frequency tuning and output power of microlasers is presented.
