Laser Alignment Heck Pt III

After several weeks of fiddling with my laser, it’s now fully working and back on the table.

Many thanks to all those at the Holography Forum who provided suggestions for getting the beast aligned.

Also many thanks to Sam Goldwasser for making public all his (and others) knowledge on lasers.

While it was sometimes difficult to grok exactly how to go about things without pictures, I would have been lost without everyone’s help.

And finally, thanks to Tom Ehrichs for spending time cleaning and aligning the laser. I gained as much by watching him work as I did by him working.

Here’s the laser fully tweaked and putting out almost 23mW.
