I. Zergioti, in Handbook of Flexible Organic Electronics, 2015. diode-pumped solid-state laser A compact solid-state laser, referred to as DPSSL, created when a laser diode pumps light into either the sides or end of gain crystal. Operating advantages The smaller size of the resulting system, lower heat generation, less electrical noise, higher safety (operating voltage of flashlamps can vary from 100 to several thousand volts and currents from tens to thousands of amperes, while the operating voltage of laser diodes is in the range from 5 to 50 V at currents from units to hundreds of amperes), easy control of pulse shape and repetition rate, easy maintenance and replacement. Diode-pumped solid state lasers for medical, material processing, LiDAR and spectroscopy appliications, as well as, for optical pumping. To emphasize the efficiency of the laser technique used in this investigation, experiments with layer removal of CF-PEEK were performed using the 355 nm laser. Major advances in solid-state laser technology have historically been preceded by advances in pumping technology. There are also some disadvantages of semiconductor lasers. This will promote the use of these sensors in smaller, more economical aircraft that are within the budget of many more regulatory agencies and maritime countries. Diode-pumped solid-state lasers tend to be much more efficient and have become much more common as the cost of high-power semiconductor lasers has decreased. Amongst the wide range of products for sale choice, Diode Pumped Solid State Laser is one of the hot items. A scientist makes an adjustment to the Mercury laser beamline. nevertheless, excimer lasers have higher pulse energy, shorter pulse duration and shorter wavelengths than DPSS lasers, so it is possible, provided that the laser beam is homogenized by a special optical system before being used for machining, to fabricate fine patterns with very high resolution with the help of masks. Using special optics, which can significantly increase the laser diode price, the quality of the beam can be improved such that it is possible to guide the radiation into an optical fiber with relatively good efficiency (Botez and Scifres, 1994). Laser … Common materials used are crystals, such as YAG (YTTRIUM aluminum garnet); alexandrite; and CORUNDUM, doped with a rare earth element such as a NEODYMIUM; ERBIUM; or HOLMIUM. A scientist makes an adjustment to the Mercury laser beamline. The “Z machine” has produced very large pulses of X rays, which should be capable of driving inertial fusion targets in future experiments. The Laser Equipment Gallery (Version 1.74 or higher) includes photos of various DPSS lasers: "Assorted Diode Pumped Solid State Lasers" has some examples of similar units (presently 20 mW and 80 mW) and "Dissection of Green Laser Pointer" shows all the blood and guts found in a first generation version of those amazingly compact and expensive 1 to 5 mW toys. @article{osti_5936923, title = {Diode-pumped solid state lasers}, author = {Fan, T Y}, abstractNote = {The use of diode lasers instead of flashlamps as optical pump sources for solid state lasers offers significant advantages such as higher efficiency and longer lifetime. A neodymium or other rare earth doped solid state laser is pumped by a matched high efficiency laser diode, resulting in a compact, high efficiency and long lifetime laser assembly. Both categories span a range of output powers from a few milliwatts to multiple kilowatts (→ high-power lasers). In the electro-optic Q-switch, birefringence of the medium is altered based on the Pockels effect resulting in the change of polarization of the light. The arrival at maturity of the technology of InGaAs/GaAs laser diode (LD) bars and stacks has led to the availability of commercial high-power pumps in the range of wavelengths 940–980 nm. Figure 12.7 shows a draft of the adopted set-up: the laser beam is conveyed by mirrors into a galvo-driven scanning head which allows moving the beam on the workpiece surface. 2 of the accompanying drawings which show a typical diode laser-pumped solid-state laser. In contrast to flashlamps, laser diodes need special treatment because of the danger of static electricity damage. Its application in PA imaging has been extensively increased because of its features and affordability. In contrast to other solid-state lasers, Pr-lasers need only a single nonlinear step for generation of wavelengths in the UV. After recalling some basics for the optimisation of the pump and of energy extraction, dedicated to the design of nanosecond and sub-picosecond YAG and tungstate-based sources of interest in this chapter, we focus on critical thermal issues. Series sense-resistor circuits are relatively small and low cost but can dissipate significant power at higher average power levels. Extended operation lifetime of pump system Operating lifetime of the laser diode can be about 30 000 hours in continuous operation; in the pulse regime 109–1010 pulses can be generated. Current feedback can be used with boost, buck, fly-back, and SEPIC control topologies. Since less energy is lost in the transfer, smaller components and less thermal management are required. THEIA is the most energetic laser in its repetition rate range delivering nanosecond pulses at different wavelengths in the near infrared (1064 nm), in the visible (532 nm) and in the near ultraviolet (355 nm). They were unable to focus sufficient energy onto a target and have converted PBFA-II to a z-pinch configuration. Femtosecond lasers are based on picosecond passive modelocked oscillators (bulk or fiber) which after one or more free space or fiber-based amplification stages are pulse compressed to yield ultrashort pulse durations typically in the range of a few fs to 700 fs. 1064nm Diode Pumped Solid State Laser. This chapter starts with some highlights on the fundamentals of three-level materials and their operating conditions. Gordinier, ... K.R. Use of new laser materials Because many of the active laser materials have very narrow absorption bands, or bands outside the spectral range of flashlamp emission, the use of selectively tuned laser diodes can be an efficient way of pumping. Its design puts an emphasis on compactness, stability and reliability so as to be optimal for the system built-in laser product. In a third step, we propose an overview of the state-of-the-art of high-energy and high-power sources in the field of YAG and KGW–KYW-based systems, and we show how to discuss orders of magnitude in the related optical performance.
