I was reviving my laser hobby... as I do feel an urge to do something practical and swing
the soldering iron once in a while, or just contemplate upon the beauty
of a beam of coherent light!
This is mainly for the fun of tinkering with electronics and building stuff, but I do a bit of holography as well, in order to have a good use of my lasers.
I also run a blog, for discussions and announcements.
Update 8-2021: high precision, low noise digital laser diode controller desktop system;
related: remarks on a low-noise linear regulator based on the LT3045
Update 12-2020: investigations of the Osram PL530 530nm optically pumped semiconductor laser (OPSL), incl driver board
Below I have set up some notes about my laser-related projects; I wish them to be helpful to other laser enthusiasts, much like I appreciated detailed help from many others.
