Default Re: help with 808nm

Are you going to be pumping crystals or just making an IR laser? If you aren't going to be pumping crystals you can probably get other wavelengths cheaper.

Default Re: help with 808nm

Yes these are very common now. Drive them at < 1.2A their voltage drop should be around 2.1v

All the best!
