Paper Abstract

A practical plane-cone resonator for the high-power, transverse-flow CO2 laser has been designed. The output characteristics of the plane-cone resonator are researched experimentally and compared with a traditional plane-concave resonator. The output mode is an approximate TEM03 mode with a resonator length of 3 m and an equivalent aperture radius of 30 mm. The beam divergence angles of the plane-concave resonator and the plane-cone resonator are 2.6 and 2.1 mrad, respectively. In the experiments that studied the misalignment characteristics, the miss rates of the output beam are 16% and 8%, respectively, when the misaligned angles of the output mirrors are both 0.41 mrad. Also, the miss rates are 20% and 5%, respectively, when the misaligned angles of the reflectors are both 0.41 mrad. The results indicate that this plane-cone resonator has a better anti-misaligned stability than plane-concave resonators.
