- The rest of your message appeared to get cut off so I'd be interested in
- hearing more about what you had in mind. The red is most likely a HeNe
- laser as you mentioned while the red and green could be Argon lasers. Or
- you could go with a tunable dye laser which is capable of many different
- colours (wavelengths). Are you working on somee project or something?
- I'd appreciate hearing more from you since I am working on a project using
- lasers myself (the diode variety at the moment).
