Red Echo

Llew R. came by this morning with three large boxes full of laser equipment. We unpacked two argon lasers, a 100-milliwatt and a 400-milliwatt, with matching power supplies. These things are BIG! We got one of them powered up just enough to generate a steady flash; I’ll have to work on these some more and figure out how to make them run properly. The boxes also came with two pairs of galvanometers, a standard 5-milliwatt HeNe with power supply, and another laser tube of unknown type. This is going to be fun.
