Thanks.. Next two lasers are going to be the 520 and a 638, This time I am assembling the host and heat sinking myself, Serious units of these wavelengths are expensive, the diodes are a bit cheaper and I want to hone my optics assembly and fabrication skills. Been doing the electronics end of this for 45+ years, so diode handling and meeting spec are no problem at all. Just for the heck of it, there is a 505 nm head and TTL for 36 bucks, just have to wait for it to ship from China.
If your new 505nm laser comes in a lab host, you can increase the driver current to get more power out of it. If it has a fan on it you needn't worry about over driving the diode as actively cooled lasers release waste heat quickly. If it doesn't have a fan, it is simple to add one.
I like the mirrored rig you have! Thanks for sharing the beams!!
Yup... It's in a "Lab host" with a power supply. I think I would investigate the diode used before pushing this. I find it odd that the laser is marketed as 100mw, when the ONLY Sharp diode of 505nm that I can find anywhere on the web is 35 mw. so either the diode is already pushed beyond spec, or the seller is fibbing. I have apprehension when claimed output power does not match known diodes.
