Hello, I tried to make a driver circuit for a 5 watt laser using an lm317 voltage regulator. the diode is supposed to consume 5 volts at 5 amps. (I know it can since I have seen it create a much brighter output with unregulated batteries). the problem is the diode only consumes 40 milliamps (measured with mulitmeter in series) running on usb power. is there a way I can force the laser diode to consume more current or build a better yet still simple driver circuit? The schematic is in this video at 2:00 into the video.Thank you for your time!
