Possibly, add a transparency slider to bouncers? e.g. setting to to 0.5 would allow one ray to pass through, while bouncing/creating a second ray off.\
This would visually reduce the brightness of the laser ray (eventually becoming undetectable and disappearing entirely, to limit the amount of rays that could be created by a single source), while reducing damage caused by it if the wavelength setting is non-zero by the dmg*(1-power)
This would possibly make them more useful for electronics
Maybe rename "Laser Boucer" to "Laser Mirror" (probably less confusing) or just "Mirror" since i think that does a better job af describing its purpose
