Self-Q-switched Cr:LiCAF laser
Journal of the Optical Society of America B, 2013 We report self-Q-switched operation of a Cr:LiCAF laser for the first time to our knowledge. Self-Q-switching (SQS) refers to the generation of a periodic train of Q-switched pulses from a laser cavity containing only the gain medium. Since SQS does not require any additional elements such as saturable absorbers or active modulators, it is far simpler ...

The master equation for passive modelocking [PDF]
EPJ Web of Conferences, 2023 Passive modelocking (PML) of lasers is pivotal in modern science and industry. Here, solving a half-century-long challenge, we present the first master equation (ME) describing PML on all time scales, from Q-switched to fundamental and harmonic ...

Layered Ta2NiS5 Q-Switcher for Mid-Infrared Fluoride Fiber Laser
IEEE Photonics Journal, 2021 We have demonstrated the stable Q-switched Er-doped fluoride fiber laser with the help of the few-layered Ta2NiS5 in the mid-infrared spectral range. We fabricated the mid-infrared saturable absorber mirror (SAM) by depositing the layered Ta2NiS5 on a ...

High average power 1314 nm Nd:YLF laser, passively Q-switched with V:YAG [PDF]
, 2013 A 1314 nm Nd:YLF laser was designed and operated both CW and passively Q-switched. Maximum CW output of 10.4 W resulted from 45.2 W of incident pump power. Passive Q-switching was obtained by inserting a V:YAG saturable absorber in the cavity.
