Cooling chip ?

[Blades and Photons]

I saw a product Peltier Thermoelectric Cooling Chip 91 watt Peltier Cooling Chip : United Nuclear , Scientific Equipment & Supplies that cools on one side and heats on the other. Can this be incorporated into a laser to increase run time?

You can get those on eBay for 3usd and it’s called TEC it is used mostly in DPSS lasers, where temperature is key factor of the process.

Yes. Although, a heatsink with forced air cooling would be required to keep the hot side cool.

A heatsink with forced air cooling alone may be enough depending on your application.

TECs are good if you need to control the temperature precisely.

Understood. Thanks guys.

I have a few of these same TECs in my stock from a purchase about five years ago. I believe I got them all for under $3.00 each. I also have some much smaller ones. I think I paid more for an 15 mm^2 than the 40 mm^2 ones.
