FAQ:

Q: What is the most powerful laser diode?

A: The LLNL laser diode arrays are the most powerful of their type ever built, producing an incredible 3.2 million watts of laser power (Photo: Damien Jemison/LLNL)

Q: What is semiconductor laser diode?

A: semiconductor laser. Also found in: Acronyms, Encyclopedia, Wikipedia. n. A solid-state laser, constructed like a semiconductor diode, in which electrons and holes come together at the junction of cathode and anode, emitting bandgap radiation as in a light-emitting diode.

Q: What is a laser diode driver?

A: Laser Diode: The function of the Laser Diode Driver is to provide current to the laser diode. The wavy arrows indicate light exiting the package. A huge array of applications exist for laser diodes.

Q: What is a diode pack?

A: A diode is an electrical one-way check valve that will let current flow in only one direction. The typical diode pack uses four diodes to accomplish this. AC current is feed in on one side of the diode pack and DC current comes out the other side. The diode pack also works the dash ammeter or indicator light.
