I like prefer the term, lasers can burn a hole in your pocket. Because it true both ways.
I actually have two NUBM44's for that purpose Alaskan, but have never got round to it. Now that's a scary thought.
What is nice about PBS is they combine the beams coaxially, one right on top of the other. However, a wave plate is needed to match up the rectangle shaped diode outputs so the polarity of both diodes have the same footprint through the cube, otherwise without the WP, it would end up being a crossed shape. Then you could follow it up with beam correction
At first I was only driving the M462 diode at 1.1 amps at which the M462 diode only outputs 1.382 watts but I bought a Super X-Drive set at 1.8 amps and one of DTR's G-2 lens from him and now it's output is up to 2.203 watts, Big difference ! :thanks: DTR !
