I have several of these tubes in each color, RED, ORANGE, YELLOW & GREEN from Laser Chorus Vipers. I am curious if anyone knows what the part numbers mean.
High End part numbers: RED are LTRR-0400DE, ORANGE LTOR-0150DE, Yellow LTYR-0050DE and GREEN LTGR-0035DE. I figure LT is Laser Tube, R/O/Y/G is the color, R is Random Polarized and DE is double ended for double output, one beam from each end. What does the 0400, 0150, 0050 and 0035 mean?
The tubes also have sharpie writing on them on the glass: I have a Red with RDE 1500.17 written on it, one with RDE 1460.2 and one with RDE 1460.7, GREENs with GDE 1584.15 and GDE 1571.5. Orange with ODE 622-8, none of my yellow tubes have any sharpie writing on them.
I also have a rare green from a Viper LTGYR-0100DE which according to a former High End employee..."The GY was a special wavelength, the primary green was about 530nm, the GY was about 550 as I recall.. Quite rare to be sure." Note: The Viper user manual says that green was 543.5nm. Unfortunately the seller I got it from packed it very poorly and it arrived with the anode mirror/end broken off. I got 8 tubes from him and the only broken one was the GY green!
Any ideas what the numbers mean and what the sharpie markings mean? Was the sharpie writing the result of some measurement during gas fill?
