摘要

A new-style discharge tube for a metal vapour laser has been designed and built. SrBr2 was successfullyused to replace the metal strontium as a working medium. Multi-line laser oscillations from resonance tometastable transition of strontium atoms (6.45um), ions (1.03um/1.O9um) and from strontium ion recombi-nation (416.2nm/430.5nm) have been obtained through longitudinal pulsed discharge. The problem of an in-compatibility reaction between metallic strontium and the discharge tube in the strontium vapour laser has beensolved. Some proposals are presented for further developments of strontium halide lasers.
