What is a Hybrid Silicon Laser?

he human eye has no heat receptors to warn the nervous system of exposure to the dangerous burning effect. An infrared sensitive camera or phosphor plate can assist in determining the optical path of an IR laser. While some lasers direct their collimated beams through infrared filters to eliminate this risk, manufacturing processes sometimes result in faulty or missing IR filters; thus it is safer to simply avoid direct eye exposure to all laser beams.

A blue laser diode's light is produced by pumping energy into a semiconductor. In laser diodes, this is done with electric current, which distinguishes them from optically-pumped semiconductor lasers that use light. This causes the electrons in the semiconductor material to briefly rise in energy level. When the electrons revert to their original energy level again, the lost energy is released as photons, producing light.
