…heat dissipation, footprint compared to (air-cooled) ion lasers
* 532 nm: no green noise, no complex resonator design required, no thermal lensing compared to Nd:YAG/ YVO4lasers
* 561nm: 4x higher efficiency/ less power consumption and heat dissipation than “yellow YAGs”
* Flexible interface…
…Class IV laser sub-system which mates a 40 Watt AVIA NX laser source with a two axis galvanometer deflector, a beam expander and an f-theta scan lens. This combination produces small focused spot sizes at the work surface, with high positional accuracy and stability, resulting in the ability to…
…ArF excimer laser beam. This technique has already helped millions of people since the early 1990s to enjoy life without glasses or contact lenses. Coherent is the leading supplier of light sources for this rapidly-expanding industry. By being the first to engineer extremely reliable,…

…collimating lens setscrew on the laser.
5. Make sure the four screws holding the SMA mount to the
dovetail are lightly seated (minimal pressure applied)--the
SMA mount needs to be able to move relative to the dovetail
to peak coupling efficiency.

Collimator Micro Lens Fiber Optic Assemblies The collimating micro lens fiber optic assemblies are designed to offer either collimation of an emitted beam or focusing of a coupling beam. The assemblies can be customized with a variety of connector types and lens shapes to suit the customer's desired…

…the pump light causes an unwanted
radial thermal gradient and often a longitudinal gradient as well, leading to strong thermal lensing
with a lens power that varies with changes in the pump power.
There are two consequences of this thermal gradient. Firstly, the refractive index…
