Understanding of Laser, Laser diodes, Laser diode packaging and its relationship to Tungsten Copper
The laser contains a chamber in which atoms of a medium are excited, bringing their electrons into higher orbits with higher energy states. When one of these electrons jumps down to a lower energy state, it gives off its extra energy as a photon with a specific frequency. The tungsten copper, alternatively, provides much lower thermal expansion rate compared to pure copper while maintain a necessary thermal conduction rate. Tungsten copper is a copper and tungsten alloy that usually consists of 10 to 50 percent of its weight in copper and the remaining portion is made out of tungsten. The higher the tungsten content, the lower its thermal expansion rate is.
