      Hello, I am trying to help a student who would like to build a LASER Harp, which sounds pretty inspiring. I know very little about LASER Diodes, but some of the components listed here seem to be able to detect signal in addition to transmit. Has anyone worked with these gadgets before - is it just a case of configuring the device differently for detection versus emission? (Data sheet suggest so, but I am not sure) - Also, 1.1mW sounds approximately Class II, so I am guessing moderately safe? Any advice gratefully received
