The green is a DPSS pointer core. The red is a singlemode diode, as is the blue. The green appears to exhibit what I would describe as a wicked mode hop about ten minutes after it's powered up. After that, it's perfectly stable as far as I can tell. I used a microscope to measure the interference pattern produced when it went through a 1/8th inch glass slide- this is as close as I can get to a fabry-perot right now, as my lab is currently set up for electronics fabrication- and the fringes didn't move at all in 20 minutes.
The blue appears to be one of the Nichia singlemode 450 blues, and the red looks like a 650nm diode of some kind. All three have transistor based current sources and run off of three volts.
