Hi,
Anyone into Raman Spectroscopy? I vate two Preocess Instruments 785 nm 300 mW diode lasers for sale. These have grating narrowed linewidth of 0.03 nm and adjustable power with electronic shutter and fiber coupler (removable). One laser has about 2K hours and the other about 4K hours. Both are capable of way more than spec power and are in like new condition. I would take $2K for the 4,300 hour laser and $3K for the 1800 hour laser. The lifetime of the diodes is about 10K hours. Lots of life left in these like new lasers. Phil 142laser (813) 974-2378
