Self‐Induced Mode‐Locking in Electrically Pumped Far‐Infrared Random Lasers
Mode locking, the self‐starting synchronous oscillation of electromagnetic modes in a laser
cavity, is the primary way to generate ultrashort light pulses. In random lasers, without a …

[HTML][HTML] Polarization analysis of random THz lasers
A Di Gaspare, MS Vitiello - APL Photonics, 2021 - pubs.aip.org
By varying the geometrical filling factor from 8% to 12% and the hole radius from 3 to 5 µm,
we investigate the interference pattern of a set of surface emitting, electrically pumped …
