Electro-optically Q-switched operation of a high-peak-power Tb:LiYF4 green laser [PDF]

, 2021
We report on an electro-optically Q-switched Tb:LiYF4 green laser pumped by a frequency-doubled optically pumped semiconductor blue laser. The electro-optically Q-switched characteristics were studied under a wide range of repetition rates from 200 Hz to

Advances in All-Solid-State Passively Q-Switched Lasers Based on Cr⁴⁺:YAG Saturable Absorber

Photonics, 2021
All-solid-state passively Q-switched lasers have advantages that include simple structure, high peak power, and short sub-nanosecond pulse width. Potentially, these lasers can be applied in multiple settings, such as in miniature light sources, laser ...

Heterostructure ReS2/GaAs Saturable Absorber Passively Q-Switched Nd:YVO4 Laser

Nanoscale Research Letters, 2019
Heterostructure ReS2/GaAs was fabricated on a 110-μm (111) GaAs wafer by chemical vapor deposition method. Passively Q-switched Nd:YVO4 laser was demonstrated by employing heterostructure ReS2/GaAs as a saturable absorber (SA).

Q switching by self-focusing [PDF]

Optics Letters, 1985
A novel passive technique for obtaining short-laser-pulse emission is presented. A cell with a high-second-order refractive-index liquid is included in an unstable laser cavity. The external self-focusing introduced by the cell at higher optical intensities reduces the diffraction losses, producing modulation of the gain and Q switching of the cavity ...

Compact high-energy Q-switched cladding-pumped fiber laser with a tuning range over 40nm [PDF]

, 1999
We describe a compact Q-switched diode pumped double-clad ytterbium-doped fiber laser. The fiber laser was bidirectionally pumped by two laser diodes (2W of output power each) via two side-injecting pump-couplers.
