Question

how can we make a blue laser?

Answer 1

that magnesium dust burns with a blue white light and that phosphorus is spontaneous energy in oxidation and ionization it seems that a similar to Neon light (ionizing AC current) shall induce the Mg3P2 or magnsium phosphide dust (vacuum born particles) to release an intense blue white light from the magnesium phosphide resonant visible spectrum ionization energy output NOTE: bunsen burner tests show which elements and compounds produce which colors in the color spectrum. this for laser energy emission and absorption frequencies. also other elements such as cobalt can produce blue spectrums, it is just that magnesium and phosphorus is the least hazardous, cost effective and environmentally safe compound. As far as making a laser, a Neon type flourescent tube, a current source with the proper voltage reference and two front sided FLAT plate mirrors where one mirror has a pin hole for output.

Answer 2

Use Gallium Nitride ....they produce Blue Laser as in the case of the blue LEDs....
You can do a bit of Googling with Blue Laser production as search option.....and you get a hell lot of information.
