Research on all-solid-state blue lasers

Optik - International Journal for Light and Electron Optics, 2015
Blue lasers have many important applications such as high-density optical data storage, biological and medical diagnostics, color displays, and submarine laser imaging and communication. High efficiency, high brightness and compactness all-solid-state blue lasers have attracted much attention for their merits.

All solid state Mid-IR laser

2011 Academic International Symposium on Optoelectronics and Microelectronics Technology, 2011
A Tm laser pumped Mid-IR all solid-state laser is reported. A thulium laser is used to directly drive a ZnGeP2 optical parametric oscillator (OPO) with 1.99μm output to generate the 3∼5μm wavelength. Diode pumped Tm:YAP laser operates on 1.99μm, repetition frequency of 10KHz, the optical to optical conversion efficiency is 28%.

Advances in All-Solid-State Ultrafast Lasers

Ultrafast Phenomena, 1996
An ideal saturable absorber for passively pulsed laser systems has instantaneous response time, is perfectly broadband, has no residual loss, and has a variable saturation fluence. Kerr-lens modelocking (KLM) is an artificial saturable absorber with some of these ideal properties.

Ultrafast all-solid-state laser technology

Applied Physics B Lasers and Optics, 1994
Passively mode-locked diode-pumped solid-state lasers can provide practical high-power laser sources with pico- and femtosecond pulse durations. We use semiconductors not only to optically pump but also to cw mode-lock or Q-switch a solid-state laser. A novel saturable absorber design, the Antiresonant Fabry-Perot Saturable Absorber (A-FPSA), allows of

All-solid-state self-mode locking of a Nd:YLF laser

Optics Letters, 1994
An all-solid-state, Kerr-lens mode-locked Nd:YLF laser is reported that uses a simple X-fold cavity with separate gain and nonlinear media. Self-starting pulses of 3 ps are reported at 1.047 microm with significant enhancements in stability and starting behavior over previous Kerr-lens mode-locked Nd:YLF lasers.

All-solid-state self-mode-locked Ti:sapphire laser

Optics Letters, 1994
An all-solid-state self-mode-locked Ti:sapphire laser is described. This laser was pumped by a diode-laser-pumped intracavity-frequency-doubled cw Nd:YLF minilaser and produced femtosecond pulses for pump powers as low as 500 mW.

All-solid-state actively mode-locked Cr:LiSAF laser

Optics Letters, 1994
We have demonstrated an actively mode-locked Cr:LiSAF laser pumped by 659-nm radiation from an intracavity frequency-doubled diode-pumped Nd:YLF laser. The laser was tunable from 815 to 915 nm, and pulses of 30-ps duration at an average power of 3.5 mW were generated.

All-Solid-State Cr:LiSAF Femtosecond Lasers

1999
Two types of all-solid-state Cr:LiSAF femtosecond lasers are demonstrated. One laser aims at generation of ultrashort pulses. Transform-limited 30-fs pulses were generated from this diode-pumped, Kerr-lens mode-locked laser with a time-bandwidth product of 0.32 by using a wide gain bandwidth of the Cr:LiSAF crystal.

All-solid-state diode-pumped eyesafe lasers

SPIE Proceedings, 1992
An eyesafe source at 1.61 J.UD with 2.1 % wallplug efficiency, is demonstrated using a Nd:YAG pumped KTP optical parametric oscillator with total peak-power conversion efficiency of 70% and an energy conversion efficiency of 47 % to 1.61 J.UD or 30% to l.54J.UD.
