    Going to get more of these in soon? Higher power?

    Getting more samples in soon that will be available from the 20mw to 100mw.

    I bought one from Laserkid21 which was sold as 35 mw output, at 12 VDC the driver needed more heat sinking, actually, anything much over 8 VDC and it needed it or would periodically blink out for a second or so every ten seconds. The problem is the driver sent with it gets too hot, the regulator transistor needs more heat sink, the whole driver gets too hot. Good news is he is getting some more robust heat sinks for the next batch and refunded me an amount on this purchase for my troubles.

    I decided to remove the module from inside the little rectangle shaped lab style heat sink and put it in a Spartan host I had which used to have a ~638 nm module in it. The 575 module is 20 x 30 mm. The Spartan host had a 20 x 80 mm module in it, so I think I can make this work but being positive ground, will need to put some .03 mm thermal tape around the module to keep it electrically isolated. I will just use some strips around the module, afraid if I use a large continuous piece, I won't be able to easily remove it later.

    My module was drawing slightly under 1 amp at 12 VDC, about .8 amps at 8 VDC which with the driver I received, was the minimum voltage for full brilliance. Tinkering, I found with an external cc power supply directly driving the diode at about 1.5 to 1.6 VDC, this module gets much brighter at 1.75 amps, I tried pushing up to 2.25 amps, didn't appear to becoming brighter and beyond that dimmed, backing it down to 1.75 amps may be slightly less output power than at 2 amps, hard to tell by eye. My LPM isn't together right now to check. I know, I might be pushing it so hard the pump diode will fail, risking it. However, if it does, I have a 980 nm fiber module I can probably use to drive it with, maybe... Appears these are driven at 980 nm, or close to it.

    Recap: Both modules 20 mm diameter. The module on the left is 30 mm long and came out of the 575 nm laser, the one on the right is 80 mm long and came out of the Spartan. The 575 nm module obviously uses a c-mount diode.

    No such refund on my end/// didnít ask,though. Ps I put on a badpip driver at 5v and still runs hot driver. 1.5a CW is a lot of heat 8-10w
