Abstract

Abstract

Based on the plano-concave resonator, a new way to choose a branch of wavelength is reported. A laser with 9.3 μm single-line output is attained by using a high average power TEA CO2 laser and the existing optical coating technology. The single pulse energy and average power are basically the same as those of the original single 10.6 μm output. It is found that the laser spots attained by shooting the heat-sensitive paper with the same laser pulse energy at 9.3 μm and 10.6 μm are significantly different. A two-wavelength windows switching device is designed, which can realize free switching between 10.6 μm and 9.3 μm lasers at the same output power level on one laser. The switch position error is less than 5″, and the sealing performance meets the requirements.
