NEW condition HIGH power laser diode bar with fast axis collimating coated lens. I tested this laser with an SDL 824 laser diode driver @ 10 Amps. and it looks perfect. There is a small ding in the top bold piece that will noy affect operation. I tested this laser with my little water cooled CPU copper block and some thermal grease between the two. I also tested it with a monochromator to verify that it is about 803nm's. It was a little cool when I tested it. Let it heat up a bit and you'll get 808nm's. This laser is missing the little positive terminal post in the center of the laser. I will provide a copper or other suitable material post/standoff that will provide a good connection. Coherent made 2 versions of this laser. One @ 50 watts and one @ 60 watts. This is the 60watt as it has 49 emitters on the bar rather than 19 as the 50 has. 19 emitters appear as little dots easy to make out while the 49 appear as a solid bar as seen in the pic. (the emitter is not that tall, the lens is just distorting the image) CW output power 60W Center wavelength 808nm Array length 1 cm Number of emitters 49 Emmiter size 100 x 1 um emitter spacing 200um Beam divergence slow axis <10* Beam divergence fast axis <35* (without lens) Threshold current 12 A Operating current 70 A Fluid flow rate 500mL/min Inlet to outlet pressure drop 10 psi recommended coolant Demineralized water (deionized cartridge in the bypass) with contamination filter <5um Please ask for other specifications if needed (Coherent 60 watt water cooled 808NM laser diode w/lens is the responsibility of Penelope Doyle) |
