QCL Primer: History, Characteristics, Applications
Hamamatsu Corporation
Since its first successful operation in 1960 at Hughes Research Labs, the laser technology has been at the center of innovation and research. Semiconductor lasers first made their appearance in 1962...
Powering Lasers: Evaluating Bench Power Supplies
Paul Corr and Patrick Klima, Arroyo Instruments LLC
A bench power supply should be thoroughly tested and characterized before it is used to power a laser. The quality of the controls and safety measures incorporated into a bench supply will need to be...
Diode-Pumped Lasers: Performance, Reliability Enhance Applications
Arnd Krueger and Scott White, MKS/Spectra-Physics
Neodymium-doped crystals and glasses such as Nd:YAG (neodymium:yttrium aluminum garnet) have long been used as laser gain materials. Optically pumped, they produce an output wavelength close to 1...
Lasers: Understanding the Basics
Coherent Inc.
Over 60 years have passed since the first demonstration of a laser in 1960. After the initial spark of interest, lasers were for a while categorized as “a solution waiting for a problem,”...
Excimer Lasers: Photonic Stamps with Micron Resolution
Coherent, Inc.
Excimers are pulsed gas lasers that deliver high output power and pulse energies in the ultraviolet and deep-ultraviolet wavelengths. This enables them to power applications that cannot be supported...
Semiconductor Lasers: An Overview of Commercial Devices
JDSU
Laser diodes vary widely in their wavelengths, powers, spectra and beam quality. Yet they share two fundamental components with all other lasers: an optical amplifier and a resonator that confines...
