While we have offered red diode lasers and refurbished ion lasers for sale for many years, we are pleased to now offer an extensive line of green laser sources for sale.  Units are both OEM modules and finished US varianced systems.  We offer lower power convection-cooled models to 200 mw, mid-range units to 3 watt, and finally high power refurbished units to 40 watts.  These lasers can be integrated into fibers, mounts, projectors, or scan systems as your scientific, industrial, or display application requires.  Our 30+ years of laser photonic experience gives you an easy path to the custom solution you require.  Tell us what you need or the problem to be solved and we will do it FAST and ECONOMICALLY.

Coherent DPSS-532
These compact (4.2" x 2.2" x 1.4") low power units include laser heads in heatsink assemblies for better power stability and drivers which can be TTL modulated to 15 kHz.   They are convection cooled and it is recommended to mount the heatsink onto a larger metal heat conductor.  The power ratings unlike other vendors are conservatively rated and include a  warranty to deliver that power over one year.  For high stability, we offer TE-cooled lasers.  Power levels are 5, 10, 20, 50, 100, 150, and 200 mw.  Prices keep dropping so call for your current quote to (818) 994-9577 or email to  GreenLasers at Holo-Spectra.

Here is an excellent quality new 1 watt green, Excel 1000,  that can be used with our CatWeazle or Cambridge scan systems.  Because it is capable of 30kHz modulation blanking to full extinction, it can be used with just an XY scanhead for very high quality extremely low divergence laser beams and laser graphics.  In the same family is a 500mw source.  Please contact us for quotes.

If you require green sources in the 2-3 Watt range, then we offer the 58 GLS series from MellesGriot.  Especially suited for beams oriented installations, these are exceptionally bright lime green laser sources from simple to use 110/220VAC power and no cooling is required.  Because they support only slow blanking modulation, they must be run with either PCAOM or third scanner blanking to be used for complex beam projections or graphics.  Contact us for these systems if you want compact and bright green beaming!
