Modeling of diode pumped metastable rare gas lasers.

Optics Express, 2015
As a new kind of optically pumped gaseous lasers, diode pumped metastable rare gas lasers (OPRGLs) show potential in high power operation. In this paper, a multi-level rate equation based model of OPRGL is established.

Diode‐Pumped Laser Operation of Tb3+:LiLuF4 in the Green and Yellow Spectral Range

Laser & Photonics reviews, 2020
Here, a diode‐pumped laser based on trivalent terbium (Tb3+) as the active ion is reported. Optical pumping of a Tb3+‐doped lithium‐lutetium‐fluoride (LiLuF4) crystal with up to 200 mW from a diode laser emitting at a wavelength of 488.2 nm enables ...

Intra-cavity frequency doubling of an electrically pumped edge-emitting 980 nm laser diode with PPLN [PDF]

, 2009
The growing trend for laser-based projection displays makes intra-cavity frequency doubling (ICFD) of electrically and optically surface emitting diode lasers in the near IR region become more interesting [1-3].

Laser emission from diode-pumped Nd:YAG ceramic waveguide lasers realized by direct femtosecond-laser writing technique.

Optics Express, 2014
We report on realization of buried waveguides in Nd:YAG ceramic media by direct femtosecond-laser writing technique and investigate the waveguides laser emission characteristics under the pump with fiber-coupled diode lasers. Laser pulses at 1.06 μm with

880-nm-Diode-Laser-End-Pumped Electrooptically Q-Switched Nd:YLF Laser With High Energy and Good Beam Quality at 1047 nm and 1 kHz

IEEE Photonics Journal, 2016
An electrooptically Q-switched Nd:YLF laser end-pumped by an 880-nm laser diode with high energy and short pulsewidth at 1 kHz is demonstrated. The asymmetry of the focal lengths of thermal lens along the $a$-axis and $c$-axis is observed, and the ...

Cryogenic cooling for high power laser amplifiers

EPJ Web of Conferences, 2013
Using DPSSL (Diode Pumped Solid State Lasers) as pumping technology, PW-class lasers with enhanced repetition rates are developed. Each of the Yb YAG amplifiers will be diode-pumped at a wavelength of 940 nm.
