Hey,
I'm a sophomore in college and I'm working on a DIY blue laser (440nm I believe), sitting on a breadboard for now. Since it's relatively high powered, I'm going to want to run it at around 1A, I'll need about 9V for the driver I'm using, etc. cookie cutter blue. The driver will be a very simple LM317 driver with a fixed current for now (basic DDL driver I think, it's what I have components for haha).
Since I'm too lazy to buy batteries that can run it well (9 volts barely get it to laze due to lack of current), how reasonable would it be to use a function generator (We have a ton of stuff in our Analog Electronics class lab) to power the laser? I'm not too positive on the calculations which is why I'm asking on here, but could I hook my laser driver up to a circuit with a full wave rectifier bridge and get the steady voltage and current that I need? My main concerns are ripple (unless a square wave could get rid of that?) and current requirements.
I have been trying to run this on Orcad/Pspice, but I have no idea what I would use to simulate the laser diode or LM317, so if anybody has any input or ideas before I try to grind through these calculations I would love to hear
Thanks for any help

P.S. Sorry if this is in the wrong section, I didn't know if it should belong here or in the experiments and modifications section.
