DIODE-PUMPED CW Nd:CaSGG LASER

Advanced Solid State Lasers, 2000
Neodymium doped germanates with a garnet structure, such as Nd:Ca3Sc2Ge3O12 (Nd:CaSGG [l]), are promising laser materials for diode-pumping.

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.

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 Nd:YLF regenerative amplifier

Optics Letters, 1992
A diode-pumped Nd:YLF regenerative amplifier operating at 1047 nm produces 88-microJ, 11-ps pulses at a 1-kHz repetition frequency. Switching of the 250-MHz seed pulses with a Pockels cell in the half-wave configuration is achieved with a contrast ratio of 20:1.

Diode-pumped optical parametric oscillator

Optics Letters, 1996
Diode-pumped optical parametric oscillation has been demonstrated for the first time to our knowledge in a single Nd:MgO:LiNbO(3) nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd(3+) ions absorb the 812-nm radiation to generate 1084-nm laser oscillation.

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.

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.

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.

Diode-Pumped Nd:LMA Laser

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 Pump Cochlear Audition Theory

International Journal of Neuroscience, 1975
A model of the cochlea is developed whereby the motion of the basilar membrane due to sound pressure in the scala media creates, through the pivotal motion of the pillars of Corti, modulated pressure on the fluid in the inner sulcus. This modulated pressure causes fluid to flow through the tectorial gap at selected longitudinal positions along the ...
