Abstract:
The results of experimental studies on enhancing the efficiency and output power of commercial repetitively pulsed copper-vapor lasers are presented. Owing to designing, technological, and circuitry innovations, the laser efficiency at the generator operation was increased up to 1-1.2% as referred to power consumed from a rectifier and up to 1.4-1.6% if referred to the power deposited into the active element. The possibility of increasing the efficiency up to 1.8 and 2.9%, respectively, is demonstrated. In the amplifier operation mode the efficiency and power were 1.2-1.3 times higher as compared with that in the generator operation mode. In the generator operation mode the output power from a Crystal LT-30 Cu active element with the active (working) medium volume of 250 cm3 achieved 37 W, while in the amplifier mode it was 44 W. For other active elements these parameters had the following values: for Crystal LT-40 Cu 350 cm3 in volume - 44 and 60 W and for Crystal LT-50 Cu 900 cm3 in volume - 55 and 70 W, respectively.
