For those following this thread, just a reminder of what I think Viesturs has.
eBay laser with controller: http://www.ebay.com/itm/Industrial-808nm-800mw-Infrared-Focusable-Laser-Diode-Module-Cutter-w-TTL-/180781956841?pt=LH_DefaultDomain_0&hash=item2a1771bee9#ht_2189wt_1080 Short URL: http://alturl.com/9t7fg Peak Wavelength : 808 nm Color : Infrared Visibility : INVISIBLE Diode Beam divergence : 12/100 deg. Emitting area : 50 x 2 µm Module Output Power : 800 mW Diode Output Power : 1000 mW Modulation : TTL Max. Modulation Frequency : 20 KHz Focus Range : 1 inch to 5 inches Warm Up Time : < 1 Minute Power Stability : %5, 20 minutes Spectral Line width : <10 nm Operating Current : 1300 mA Operating Voltage : 9-12 Vdc Laser Diode Cooling Mode : Aluminum Heat Sink Driver Cooling Mode : Aluminum Heat Sink Expected Lifetime : 5000 hours Power Supply Required : 9-12 volts DC 1.3 Amp Applications : CNC Cutting, Material Processing, http://www.listingfactoryhost.com/users/kerimkale/eBayAuctions/346554dgf/images/DSCN6716_360697722_thumb.jpg Short URL: http://alturl.com/fynsz http://www.listingfactoryhost.com/users/kerimkale/eBayAuctions/346554dgf/images/DSCN6705_865650630_thumb.jpg Short URL: http://alturl.com/j4aof I suspect the power to the laser driver just needs to be switched as an Enable, with the driver's TTL input modulated by PWM/PDM to turn the bean on and control the strength. I have zero experience with lasers, so grains of salt are recommended. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
