A green laser pointer is a frequency doubled Nd:YVO 4 diode-pumped solid state laser . Nd:YAG can be also made to lase at its non-principal wavelength. The line at 946 nm is typically employed in "blue laser pointer" DPSS lasers, where it is doubled to 473 nm. Physical and chemical properties of Nd:YAG
Laser microphone. A laser microphone is a surveillance device that uses a laser beam to detect sound vibrations in a distant object. It can be used to eavesdrop with minimal chance of exposure. The object is typically inside a room where a conversation is taking place and can be anything that can vibrate (for example, a picture on a wall) in ...
