Laser diode 4W 808NM yag dpss pump sdl-2382-P1 coherent
Here is a NEW 4 watt, 808nm infrared laser diode in a High Heat Load (P1) package. This was made by Spectra Diode Labs (SDL) which is now part of JDS Uniphase. It is model number SDL-2382-P1.
* Package: P1 High Heat Load Package
* Center Wavelength: 808 ( 3) nm
* Slope Efficiency: 0.9 W/A typ
* FWHM beam divergence: 12 degrees parallel, 34 degrees perpendicular to junction
* Threshold Current: 2.0A typ
Operating Current: 6.3A typ
Click here for the complete data sheet for the 2300 series from the JDSU web site. There are several different diodes in the 2300 family. Be sure to look at the 2380 section for the correct data for this part. The P1 package includes a photodiode for output power monitoring, a TEC for temperature control and a thermistor for temperature monitoring.
These make excellent pump diodes for a DPSS laser system. 808nm works well for pumping Nd:YAG and Nd:YV04. With appropriate optics and crystals, you could get 200mW or more of 532nm green. These work well with the vanadate + KTP composite crystals made by Casix to produce 100 or more mW of green. Also, this diode will fit some commercial 200-500mW DPSS laser systems including the popular Coherent Compass 532-400 so it might be just the replacement you need to repair a weak or dead DPSS laser system.

* This laser diode must be attached to a heat sink if before it is powered. Failure to keep the diode cool will dramatically reduce it's operating lifetime and may permanently damage it.
* The output of this laser diode is nearly invisible. Don't let this fool you - it is powerful enough to set things on fire and can cause burns and permanent eye damage. You should always wear appropriate safety goggles when working with high power laser devices such as this.
