I have a couple of IR, red and green laser diodes. Experiments with red and
green lasers are relaively easy as they are visible.
Can you recommend any simple, practical, method (I am hobbiest with limited
budget) to make both IR and red laser beams coaxials ei.alight both the IR
and the red laser beams in such a way that IR laser spot always (even at
long distances) on the same position where the red laser spot is ?
If I can make them coaxial then I can turn on the red laser, find it spot
and switch it off and turn on the IR laser on for IR laser experiments.
IR can be seen on i.e. displays of digital cameras (no special camera is
required). Sometimes this is used to check if an IR remote control still
functions. Maybe that's a solution?

Hey kids..... ... It doesn't seem that long since a club laser was typically an argon unit with a water cooled head. ... Now with DPSS greens and surprisingly high power "normal" red lasers the cost of a scanning club laser has crashed to very affordable levels. ... It's rated 50mW but because green lasers use a much higher power infra red diode to stimulate a crystal to lase in a different wavelength, then double it's output frequency with another crystal the power dissipation tends to be pretty high compared to a conventional red laser diode.... At the back of the unit is a transformer for the fan, steppers and control card, while the lasers themselves are surprisingly controlled by two independent mains powered switch mode supplies stacked on top of each other. ...
