My boss asks me to get a tubale laser which can involve the wavelength ranging from 760 nm to 800nm, however..............with fairly little money T_T One of the best suggestion is to assembly a laser system by ourselves, so we need a laser diode (with tunable function), a power supply and... -

Can we paint an invisible laser beam to make it visible?
We have a 700nm laser diode for some specific use, however, now we need to use this laser diode for alignment, however, it's invisible....... Some colleague come up with a solution that maybe we can color the laser beam with a special color or pigment to make it visible, ignoring any distorion...
