Passively Q-switched ceramic Nd3+:YAG/Cr4+:YAG lasers.
Passively Q-switched ceramic Nd3+:YAG lasers with ceramic Cr4+:YAG saturable absorbers are demonstrated. When the lasers are pumped by a 1-W cw laser diode, optical-optical efficiency as great as 22% is obtained with Cr4+:YAG of initial transmission ranging from 94% to 79%. The results are similar to those in their crystalline counterparts. The operation of Brewster's angle and the polarization...
متن کاملFrom Flashlamp-Pumped Liquid Dye Lasers to Diode-Pumped Solid-State Dye Lasers
Dye-laser technology has seen very significant progress over the last 39 years since the first demonstration of this device technology. Dye lasers offer efficient emission in the visible and near-infrared bands by direct generation of laser light. The initial emphasis was on the liquid-phase technology, and is the one very successful liquid laser. More recently the research emphasis has been so...
متن کاملHigh power VCSEL array pumped Q-switched Nd:YAG lasers
Solid-state lasers pumped by high-power two-dimensional arrays of vertical-cavity surface-emitting lasers (VCSELs) were investigated. Both end-pumping and side-pumping schemes of Nd:YAG lasers with high power kW-class 808 nm VCSEL pump modules were implemented. For one application 10 mJ blue laser pulses were obtained from a frequencydoubled actively Q-switched VCSEL-array dual side-pumped Nd:Y...
متن کاملCharacteristics of Q-Switched Cladding-Pumped Ytterbium-Doped Fiber Lasers with Different High-Energy Fiber Designs
We theoretically and experimentally analyze Q-switched cladding pumped ytterbium-doped fiber lasers designed for high pulse energies. We compare the extractable energy from two high-energy fiber designs: 1) singleor few-moded low-NA large mode area (LMA) fibers and 2) large-core multimode fibers, which may incorporate a fiber taper for brightness enhancement. Our results show that the pulse ene...
متن کاملLasers and their Applications
Ever since the advent of the first LASER (acronym for Light Amplification by Stimulation Emission of Radiation) in 1960, there has been a steady increase in the application of lasers. Applications have kept on becoming more and more diverse as the capability of the lasers have increased. In this chapter we will enumerate and classify many of the applications of lasers and then go on to discuss ...
