Album: Fun with LASERs

I decided to see if I could mix light from three LASERs. Red, green and blue. The green is much brighter than the others and the red is brighter than the blue. It was therefore necessary to PWM the red and green to get a good mix. <br /> By using a 50% duty cycle on the green and 65% on the red I could get a good white light when mixed with the blue. They run on a 555 and are fired with a FET.
