Coherent Infinity Laser Description

flat top beam profile
Flat Top Beam Profile

The Coherent Infinity is a 40 Watt, short pulse, single mode, dual pass, flashlamp pumped Nd:YAG laser. With a flat-top profile, beam quality <1.5 M2, a user defined repetition rate from 0.1 to 100 Hz, and configurable with on board, SHG, THG, FHG, OPO, and beam expansion options, this laser is age proven, and still one of the more versatile lasers for your physical science lab.
