    No duty cycle?

    I have an LPC-815 seated in an aixis module and attach to Odic Force Alloy Module Holder/Heatsink (12mm). I drive it at 245mA. Do my heatsink good enough and current low enough to give me a no duty cycle of laser fun?

    advice on my driver

    This is my driver for my LPC-815. I am powering it with a non-regulated 12V 500mA power adapter. I wonder is this a safe driver to use and also able to pro long my LPC-815 life? Any comment on my driver is most welcome.

    LPC-815 Led

    My LPC-815 just went led. It have been working fine for the past 1 week. My driver was base on LM317 DDL circuit(I just add additional LM317 in front to lower voltage). My driver is powered by a switching mode power supply 12v 1.7A. Using 2 LM317 for my driver. The first LM317 lower the voltage...

    Need help with my build. (First time)

    Hi all, Let me introduce to my first >5mw laser. =D From left to right: 4 x 1.5v (AA) in series, 2 x LM317 (simple voltage and current regulator), a few resistor to control the voltage and current and lastly my laser diode at its home. =D I choose to have 2 LM317 so that I can any power...
