Neodymium YAG laser pumped with radiation from high frequency electrodeless discharge
Abstract
A system for pumping a solid state laser employing electrodeless discharge is described in which the annular cavity of the lamp consists of three ballast cavities: the main (discharge) cavity and two additional cavities placed coaxially on both sides of the main cavity. The system provides enhanced longevity (approximately 1000 hours) and superior stability. Continuous lasing power exceeding 25 watts is provided in all modes. The system has withstood 75,000 cycles with no significant degradation in output parameters. It is suggested that progress in the development of efficient power sources operating at 27.12 MHz will improve the efficiency of the laser significantly and make them competitive with traditional lasers.
