Corner-cube retro-reflectors (CCR) and axicon lenses with 90 degrees apex angle (AL) are optical elements with interesting reflective and polarization characteristics. In our previous reports, we presented and discussed basic polarization properties of AL and CCR retro-reflectors and comparative lasing characteristics of Fabry-Perot (FP), CCR and AL resonators at cryogenic temperatures. To explore the potential benefits of the CCR and AL resonators, we have started lasing experiments using these elements at ambient temperature conditions. Efforts are made to demonstrate lasing potential and advantages of CCR and AL resonators under high thermal load conditions.
