Transverse pattern modifications in a stable apertured laser resonator
- Tel Aviv University, Department of Electron Devices, Materials Electromagnetic Radiation, Ramat Aviv, 69978 Tel Aviv, Israel (IL)
The effects of hard apertures on the transversal mode distribution and the output near and far field distributions are investigated both theoretically and experimentally. Wavefronts propagating in different directions inside a CO{sub 2} laser cavity were measured at the same plane and found to have different transversal amplitude profiles. The influence of intracavity aperture's location and diameter on the near field distribution and far field beam quality were measured and calculated. Quantitative figures of merit are introduced to evaluate the departure of the transversal mode patterns from ideal Gaussians.
