Lateral displacement of the mode axis in a misaligned Porro prism resonator.
The lateral shift of the mode axis in a misaligned Porro prism resonator is analyzed. A method to find the tilted mode axis in a misaligned Porro prism resonator is introduced. Expressions for the displacement of the mode axis are deduced. They predict that the lateral displacement of the mode axis is proportional to the horizontal misalignment angle beta and highly dependent of the prism azimuth angle theta. Experimental results obtained agree well with theory.
Laser resonator design using optical ray tracing software: comparisons with simple analytical models and experimental results
Software simulation of complex resonator and optical system designs offer the potential to couple traditional opto/mechanical tolerance analysis with the required system performance. One such a software platform, ASAP, and the methodology to perform tolerance analyses has been evaluated and validated for the case of the crossed Porro resonator. Simulation results and experimental measurements are presented and discussed.
Flat-Roof Resonators
A microwave or laser resonator with flat-roof mirrors is discussed from a theoretical point of view. When the angle of the roof is extremely small, on the order of 10−3 rad for microwaves or 10−3–10−6 rad for optics, this resonator has some features in common with the confocal resonator.
