In the autumn of 2003 the US Department of Defense launched an ambitious program to create diode lasers that are 80% efficient at converting electricity into light. Dubbed SHEDS (standing for ...
The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...
