Abstract

Improvement of beam quality is a major task in most of the laser systems. To optimize the performance of copper vapor laser system, beam propagation in an injection-controlled copper vapor laser system is investigated on account of thermal lens effect. Far-field intensity distribution as well as its temporal evolution of the output from a copper vapor laser oscillator at different operating conditions are measured in detail. Experimental observation has bene performed about the influence of delay time between the oscillator and amplifier on the far-field intensity distribution of the output from the amplifier. The application of a single-pass unfolded amplifier model has been successfully demonstrated to describe beam propagation within the system.
