High-performance diode-pumped Nd:YLF amplifier
Applied Optics, 2003We report on the performance of a multipass diode-pumped amplifier design to provide a combination of high gain and efficiency with high stability. A simple rod-cavity design and the establishment of quasi-steady-state operation resulted in a saturated gain of over 6000 at an average output intensity during the pulse train of 7 kW/cm2.

Diode-Pumped Organic Semiconductor Microcone Laser
IEEE Photonics Technology Letters, 2011We report laser action from conical polymeric microcavities. A thin film of the organic semiconductor tris(8-hydroxyquinoline) aluminum (Alq3) doped with the laser dye 4-dicyanmethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM) on top of the microcones enables low-threshold lasing when pumped with a conventional blu-ray laser diode.

SPIE Proceedings, 1990
Since the invention of diode lasers in the early 1960's there had been continuous investigations in laser diode pumped solid state lasers as has been reviewed in detail by a number of papers ( see e.g. [1] ). There are two main advantages of using diode lasers instead of flashlaraps as a pump source for solid state lasers: First the emission of ...

Diode-pumped, continuous-wave Tm:YAIO_3 laser
Applied Optics, 2006A continuous-wave, diode-pumped, room-temperature Tm:YAlO3 laser was built, characterized, and compared with a theoretical model. Spectroscopic parameters of the laser crystal, such as the pump band ((3)H4 manifold) lifetime, the upper laser level ((3)F4 manifold) lifetime, and the absorption coefficient were measured.

Directly diode-pumped holmium fiber lasers
Optics Letters, 2007Sensitizer-free holmium-doped silica and fluoride mid-infrared fiber lasers are pumped using a high-power diode laser operating at 1148 nm. A maximum output power of 162 mW at 2.86 microm was produced at a slope efficiency of 24% using Ho(3+), Pr(3+)-doped fluoride fiber.

Multicolor diode-pumped upconversion fiber laser
Optics Letters, 2010We present a new method to control the power of individual spectral components of a multicolor laser by mirrors with variable air gaps and by a composite resonator configuration. We demonstrate a Pr/Yb-ZBLAN fiber laser with arbitrary spectral composition of three simultaneously emitted components at 492 nm, 520 nm, and 635 nm.

Efficient laser diode pumped Nd lasers
Applied Optics, 1989Results are presented for laser diode axially pumped Nd:YAG and Nd:BEL lasers. For Nd:YAG, in excess of 870 mW was obtained with a differential slope efficiency of 56%, and for Nd:BEL in excess of 635 mW was obtained with a slope efficiency of 46%. Electrical efficiencies of 13.0 and 9.5% were recorded for Nd:YAG and Nd:BEL, respectively.
