Chromacity 520

A robust 520 nm femtosecond laser for biomedical imaging and semiconductor applications

The reliable 520 nm femtosecond laser is a fixed wavelength source that delivers ultrashort-pulses with high average powers in the green.


Pumped by high quality pulses from our Chromacity 1040, second-harmonic light at 520 nm is efficiently generated with sub-150-fs pulse durations.


This SHG module can be coupled with the Chromacity 1040 to generate up to 2 W of average power.  Applications include the detection of photomask defects via an ultrasonics technique and fluorescence lifetime measurements.


The compact housing enables simple system integration, and a fiber delivery option is also available.
