Staggered hollow-bore CO2 waveguide laser array

Abstract

A modified hollow-bore ridge waveguide, utilizing a staggered ridge geometry, has been used successfully to obtain single-frequency operation from an array of CO2 waveguide lasers. The gain volume of the array is equivalent to six waveguide lasers of 37 cm length and 2.25×2.25 mm2 cross section. The output power from the sealed-off device reached 68 W cw. Stable single-frequency operation in the antisymmetric supermode was observed.

“…described by Degnan and Hall,6 the standing wave conditions for the waveguide modes are 1rn1 + k(11 + '2) = q'rr(q = 1,2, ...) , (2) where 'l and '2 are the distances from the waveguide ends to the optical resonator mirrors and 1 is the length of the waveguide. From Eqs.…”

The research of phase-locking of more discharge tubes for two-dimensional axisymmetric-fold combination resonator CO2 laser

“…In recent years, array lasers and r-f excitation technique become popular [1,2], which are used in hollow bore ridge staggered CO 2 laser array, leaky-mode-coupled laser array, limit parameter wave-guide CO 2 laser array, groove-coupled strip waveguide CO 2 laser array [3][4][5][6]. These lasers can obtain phase-locking coherence output but the further improvement of output power is restricted by the small width of single lasing unit Then the concept of area-scaling is introduced into array lasers which obtain successful results [7][8][9].…”
