Hello, I have a few lasers so far, hoping to get bigger and better ones

Hello,
I am a university student from Canada I have two lasers so far: DX 200w red, DX romisen 30mw. I'd like to venture into blu-ray and hopefully more especially with the help of LPF. I've read up alot already, but still have one thing to decide how much current I should use on a PHR. I'm looking to burn, but I don't have the funds to risk burning out diodes anytime soon. I'm thinking 120ma.

I run them with a rkcstr driver at 125 to 150 and get excellent results
but you can easily read up on this on the stickies welcome aboard BTW

Welcome to the Forum. :wave:

I have my PHR set at 125mA.

Welcome to the forum!

My PHR is set at 156mA and is still kicking.

Hey John, the awesome Core Blu-ray you built for me works great still, it was just under 140 mW using the acrylic lens, but with the jayrob glass 405 lens it's over 175 mW on my meter! This unit seriously burns! Thanks Again John! -Glenn
