Er: YAG laser rod—50% Erbium-doped in YAG
Arsuf lasers advanced MATERIAL When coming to source an Er: YAG 50% laser rod there are 2 major parameters to be considered. Slope efficiency of output energy and threshold of input energy, a figure that tells us when the rod will start lasing. The variation in regard to these 2 specs among vendors is large […]
Our win at the Thin Film Laser Damage Competition 2021 at SPIE Laser Damage
We entered our product in a thin film damage competition held by the prestigious Lawrence Livermore National Laboratory in California, the Thin Film Laser Damage Competition and won multiple times in a row. The event is held every year as part of SPIE Laser Damage, which is the annual meeting for laser damage materials and thin films used with high energy and high power lasers. Laser damage is […]
Holmium laser rods uses in medical industry
The solid-state, flashlamp-pumped Holmium: YAG (yttrium-aluminum-garnet) laser can remove tissue and make blood clot faster. It has been used since the 1960s in surgery, especially in urological applications. The benefit of the 2100nm wavelength is that it is highly absorbed by tissue and water. When the laser beam is fired into an aqueous medium, a […]
All you need to know about Nd:YAG Laser
What is Nd:YAG Laser? Neodymium-doped ytt rium aluminium garnet (Nd-YAG) crystal is a common lasing medium used in solid state lasers. It has been used and researched since 1964. The laser is designed by replacing a few yttrium irons in the crystal structure of the garnet with neodymium irons. The ions of YAG and yttrium […]
High LDT Holmium rods
Holmium is a rare earth metal or lanthanide, twenty times more abundant than silver in nature. It has properties similar to erbium, another lanthanide. In its elemental form, the element is a silvery-white metal, soft and malleable. Pure holmium is slowly attacked by water and oxygen and dissolves in acids. It is stable at room […]
6 Common Laser Rod Faults
Manufacturers go through a lot of trouble to design and build laser rods that can withstand the energy and power levels of their typical application environments. Despite all their precautions, there is a probability that some damage will occur to laser rods during normal operation. Laser damage may be driven by adsorption or by dielectric […]
Gain media for solid state lasers— Doped glasses compared to doped crystal
Solid-state lasers are based on gain media such as glass or crystals. Both glass and lasers are used by optically pumping them with light, so they can amplify light in other spectral regions, usually at longer wavelengths. Usually, laser glasses (typically phosphate and silicate glasses) are doped with trivalent rare earth metal ions like Nd3+, […]
What are Alexandrite Rods?
An Alexandrite rod is a solid-state chromium-doped laser useful in dermatology and other medical applications. You’ll find alexandrite gemstones in nature. But for medical uses requiring high crystal quality, the Cr3+:BeAl2O4 crystals are grown using a modified Czochralski method. This chromium-doped beryllium aluminate material can also be used for Lidar or Light Detection and Ranging […]
Laser Damage Threshold Test of Improved Coating Process for Erbium Glass Products
Background of Test Log Nr. 57684 The Erbium glass products delivered by ARSUF LASERS were continuously suffering laser damage failures due to quality variations across batches. Customers had specified a Laser Damage Threshold (LDT) target of above 20j/cm2 as the standard. This target was given to the best coaters in China and Europe, who achieved […]
Efficiencies and cost-savings in thin-film coatings for semiconductor lasers
The flourishing semiconductor microelectronics equipment industry can lend its practices to the semiconductor laser industry to engender cost savings and efficiencies. The fast-growing but still relatively small semiconductor laser market relies on a lot of the same tools as the microelectronics equipment industry, such as PVD equipment (physical vapor deposition), but at a smaller scale. […]
