I just returned from vacation to Hawaii with my unofficial "girlfriend." I just want to say that Hawaii is awesome.
Anyway... I have lots of spare diodes, heatsinks, crystals, drivers, etc. from lasers and disc reader/burners that were sacrificed for the good stuff. I hate wasting parts so I decided I would try to make use of some of my "scraps."
I slapped a 0.3W 808nm diode in front of a crystal set from an X50 and put it in a heatsink with a bit of thermal glue.
The crystal set was pumping out 61mW peak in the stock CNI assembly.
In the setup I threw together I am getting 94mW unfiltered and 82mW filtered peak power.
The power drops rapidly after a 30 seconds as the module warms up, but the average power is about 50mW 532nm for a couple minutes. It runs in TEM00 with no hops.
I didn't bother measuring pump power or current draw because this was really just an experiment to do something new. I used the diode and driver from 2 different 5mW greens and a heatsink from another. I used a larger brass heatsink over that module for extra cooling and to make a nice fit into the new version dilda host. There is a lot of room for perfecting this module... but as a laser built with scraps, it's fine as it is.
Here are pictures.
I used some heatsink from a 6X sled to keep the driver cool.
In comparison to a 120mW X105:
