Non-symmetrical vortex beam shaping in VECSEL laser arrays
Sopfy Karuseichyk, Ilan Audoin, Vishwa Pal +1
We propose and numerically test a novel concept for asymmetric vortex beam generation in a Degenerate Vertical External Cavity Surface Emitting Laser (DVECSEL). The method is based…

Phase Sensitive Amplification Enabled by Coherent Population Trapping
Pascal Neveu, Chitram Banerjee, Jasleen Lugani +3
We isolate a novel four-wave mixing process, enabled by Coherent Population Trapping (CPT), leading to efficient phase sensitive amplification. This process is permitted by the exp…
