RF Excited Slab Waveguide Array C02 Laser With Mutual Injection Phase Coupling

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]. The output power of these lasers is higher but the limited r-f excitation source restricts its output power and complex resonator technique increase the cost of the whole devices.…”
