Diode Pump Cochlear Audition Theory
International Journal of Neuroscience, 1975A 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 ...

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.

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 ...

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.

SPIE Proceedings, 2007
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.

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 continuous-wave Nd:glass laser
Optics Letters, 1986We report on diode-laser pumping of monolithic Nd:glass laser oscillators. End pumping with a single-stripe diode laser, a threshold of 2.2 mW, and a slope efficiency of 42% were observed on a 2-mm-long oscillator with a mode radius of 35 microm. The oscillator generated 2.5 mW of single-ended output power in many (>20) axial modes.

Diode pumped, frequency doubled LiSAF microlaser
Optics Communications, 1998Abstract A new diode pumped, solid state, Cr:LiSAF/KNbO 3 microlaser has been developed which simultaneously produces 50 mW of infrared fundamental power and 0.37 mW power at its second harmonic at 430 nm.

Annual Meeting Optical Society of America, 1989
Interest in diode laser pumped solid state lasers has increased dramatically in the past few years due to their advantages over lamp pumped devices and improvements in diode lasers. This has led not only to better performance for 1.06- and 1.32-µm Nd doped lasers, but also to demonstration of a number of novel diode pumped devices.

Diode-pumped grazing incidence slab lasers
IEEE Journal of Selected Topics in Quantum Electronics, 1997Diode-pumped grazing incidence slab (GISL) lasers, and materials which may be used with this configuration, are discussed. Of the materials investigated so far, Nd:YVO/sub 4/ has been shown to yield high efficiency and high small-signal gain, and a compact, 1-kHz repetition rate laser, using a Nd:YVO/sub 4/ slab has generated 3-ns duration, millijoule ...
