Diode-pumped Cr:LiSrAlF_6 laser

Optics Letters, 1991
A Cr:LiSrAlF(6) laser is diode pumped with both commercial 10-mW visible laser diodes and a higher-power 100-mW cw, 265-mW pulsed diode. Polarization combination of pump diodes to reach threshold is demonstrated with two low-power lasers. Pumping with the high-power diode produced powers of 19.9 mW cw and 78 mW pulsed.

GaAs Laser Diode Pumped Nd:YAG Laser

Applied Optics, 1974
A 1.5-mm by 3-cm neodymium-ion doped YAG laser rod has been side pumped using a GaAs laser diode array tuned to the 8680-A absorption line, achieving a multimode average output power of 120 mW for a total input power of 20 W to the final-stage laser diode drivers.

Diode-pumped femtosecond Yb:CaNb_2O_6 laser

Optics Letters, 2011
We report to our knowledge a diode-pumped passively mode-locked Yb:CaNb(2)O(6) (Yb:CN) laser for the first time. Both CW and passive mode-locking operation of the laser are experimentally investigated. A maximum CW output power of 1.4 W with a slope efficiency of 20% is obtained on a 7 mm long 1.5 at.% Yb:CN crystal, while stable passive mode-locking ...

Diode-pumped microchip Er–Yb:glass laser

Optics Letters, 1993
A single-frequency, diode-pumped, Er-Yb:glass microchip laser at a 1530-nm wavelength has been designed and operated. An output power of greater than 25 mW, a linewidth narrower than 1 kHz, and a slope efficiency of 22% have been obtained.

Ultrafast Diode-Pumped Lisaf Lasers

Conference on Lasers and Electro-Optics Europe, 1996
LiSAF crystals (LiSrAlF6 doped with Cr3+ ions) are very interesting amplifier materials due to a large fluorescence bandwidth in the near infrared (800 nm to 1 μm) and an absorption band in the red (600-700 nm). Commercial high power single-stripe laser diodes emitting in this wavelength band are available since a few years.

Terawatt diode-pumped Yb:CaF_2 laser

Optics Letters, 2008
We present what we believe to be the first terawatt diode-pumped laser employing single-crystalline Yb:CaF(2) as the amplifying medium. A maximum pulse energy of 420 mJ at a repetition rate of 1 Hz was achieved by seeding with a stretched femtosecond pulse 2 ns in duration, preamplified to 40 mJ.

Diode-pumped Yb:Y2O3 ceramic laser

Applied Physics Letters, 2002
We report on a diode-pumped polycrystalline Yb:Y2O3 ceramic laser. We demonstrate that, with a pump power of 11 W at 937 nm, 0.75-W cw laser output at 1078 nm can be obtained from the laser. The laser had a threshold of 4.7 W and a slope efficiency of 12.6% when an output coupler of R=98% was used.

Laser-diode-pumped Nd:YAG active-mirror laser

Applied Optics, 1997
We 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.

Frequency-stabilized laser-diode-pumped Nd:YAG laser

Optics Letters, 1989
We describe a frequency-stabilized diode-pumped Nd:YAG laser that is actively frequency stabilized relative to a reference Fabry-Perot cavity using the Pound-Drever technique. We describe the servo loop and the measurement of its noise and gain performance and demonstrate its ability to reduce the laser frequency noise close to the shotnoise limit of ...

Laser-Diode-Pumped Alexandrite Laser

Advanced Solid State Lasers, 1991
We report the first operation of a diode-pumped alexandrite laser. A compact alexandrite resonator with a threshold of 12 mW was longitudinally pumped by two 680 nm laser diodes.
