This Laser Turns Infrared into BLUE

With powerful enough lasers, the world starts behaving very differently. Using a nonlinear optical process called second harmonic generation you can merge pairs of photons in a laser beam to create a single photon with twice the energy. This means that one color of light is turned into another.

In practice this is done with infrared lasers which when shot through a special crystal merge to form a color like blue or green depending on the setup.

The laser I'm using I got online for less than $100, but it contains a 2.5w IR (808nm) laser, and a 50-100mw blue (473nm) laser. The machine itself is also a decommissioned Raman spectroscope, which I'll be trying to repair.
