4+W Red Laser Plug & Play- Corrective Tight Beam/Analog Modulation PSU-TEC

Description

Plug & Play 115 VAC over 4 Watts, measured 4200mW of Brilliant Red Laser with Corrective Tight Beam/Analogue Modulation w/ PSU-TEC Cooling.
I paid 00 for just the head/PS, I added the TEC cooling and system heat sink. Priced for quick sale. Extremely powerful laser for any wavelength particularly red, I measured 4200 milliwatts then never ran the laser again until I fired it up for the pics in this eBay listing end of April. Comes with complimentary safety glasses required for these extremely high power levels. After buying the head/PS for 00 I bought 0.1mm Indium foil and mounted the head to a cold plate for intimate thermal coupling of the head to the heat sink which has the TEC between the cold plate and finned heat sinks. This still needs to be hard mounted for unlimited operation but everything is included ready for bolting. The laser can be tuned to any power level from a few milliwatts to full power with a 0-5VDC power supply or a battery/Pot. arrangement. The laser runs at full power as is but is limited to 1-2 minutes until the TEC is connected then you have a powerful red laser worth four times your investment This would be a awesome light show laser with a 2 Watt green and 5 Watt blue laser combined into a single >10 Watt white laser beam.
Thank You.
