YELLOW HeNe Laser Melles Griot 05-LYR-161 Yellow Laser 594 nm Plug and Lase!

Description

Here is a randomly polarized (dual orthogonal) HeNe laser head with matching power supply made for the YELLOW line at 594 nm. This is a 2 mW minimum specification laser outputting ~3.5 mW after full warmup with a multi-mode beam.  The beam specification is multi-mode but the beam divergence is only 1.01 mR so this indicates a high % TEM 00 spatial mode content (but not 100%). The yellow line is the 2nd rarest of the visible lines to find. Pure 594 nm. The previous owner removed the model number sticker but at Sam's laser FAQ we just sniff them and we know.  OK, we measure the head voltage at 6.5 mA. :) Yellow laser! Did I mention Yellow? Rare to find these.  Power meter and laser stand are not included, just the laser, power supply and a line cord. Thanks for looking!
