Conference on Lasers and Electro-Optics, 1986
A high efficiency laser diode array pumped Nd:YAG solid-state laser has recently been demonstrated.1 We report for the first time a diode array pumped rare-earth laser other than Nd. Laser action was observed on the trivalent holmium 5/7 → 5/8, 2.1-μm transition.

Advanced Solid State Lasers, 1992
A pulsed Nd:LMA laser has been demonstrated using laser diode array pumping. This material is attractive since high Nd concentrations can be achieved while maintaining a reasonable upper laser level lifetime. Experimental results for a-axis pumping of this uniaxial material show potential for high efficiency.

Diode-pumped Nd:MgO:LINbO3 laser
Annual Meeting Optical Society of America, 1986Laser action in Nd:MgO:LiNbO3 was recently demonstrated by pumping with a rhodamine 6G dye laser operating at 598 nm. MgO-doping substantially reduced photorefractive damage in Nd:LiNbO3 but did not eliminate it entirely. True cw room temperature laser action was possible for propagation along the c axis (F‖c) but not for ...

Laser Physics Letters, 2016
This letter reports diode pumping for dye lasers. We offer a pulsed dye laser with an astigmatism-compensated three-mirror cavity and side pumping by blue laser diodes with 200 ns pulse duration. Eight dyes were tested. Four dyes provided a slope efficiency of more than 10% and the highest slope efficiency (18%) was obtained for laser dye Coumarin 540A

2018 International Conference Laser Optics (ICLO), 2018
This study presents tunable laser oscillator based on diode-pumped Cr:Zn x Mn 1-x Se single crystals. Pulsed oscillations in tunable ranges 2290–2578 nm and 2353–2543 nm were demonstrated for Cr:Zn 0.95 Mn 0.05 Se and Cr:Zn 0.70 Mn 0.30 Se and the peak output power up to 177 mW and 94 mW, respectively.

SPIE Proceedings, 1995
A dye laser pumped by AlGaInP laser diodes produced efficient, low threshold operation at wavelengths between 740 and 800 nm. Rhodamine 700, oxazine 750, DOTCI and oxazine 1 dyes were demonstrated. Optical conversion efficiencies approaching 50% and output power as high as 360 mW were obtained when pumping with a DCM-based dye laser.

Laser-diode-pumped Nd:YAG active-mirror laser
Applied Optics, 1997We describe a simple design, laser-diode-pumped cw Nd:YAG active-mirror laser and present a thermal analysis of the crystal. A cw output power of 2.4 W and an M(2) beam quality value of less than 1.9 at an incident pumping power of 8.9 W were obtained.

Crystals for lasers with diode pump
SPIE Proceedings, 1996Results of the latest research of the record characteristics of diode-laser pumped solid-state laser and physical properties of crystals for these lasers are discussed. Crystals, possessing one optical axes and having strong polarization dependent physical properties, and, first of all, absorption coefficient on a length of a diode pump wave and ...

In this paper we describe the design and performance of diode-pumped organic lasers based on the poly(paraphenylene-vinylene) derivative MEH-PPV. To achieve the very low oscillation thresholds required for direct diode pumping, we use a novel surface-emitting distributed Bragg reflector cavity.
