A new class of applications are being pursued with QPC Lasers because of their high brightness, high efficiency and power performance.

Application: Defense
Because of their compact size and light weight and ruggedness, semiconductor lasers are ideal for military and aerospace applications. Used directly or as pumps for other lasers, semiconductor lasers are used in a wide variety of applications including both the transmission optical energy to a target and receiving a portion of it back in order to measure various physical properties of the target in a remote fashion.

Defense lasers that transmit energy to the target are common at both low and high power levels. On the low power end (<500mw), direct="" diode="" lasers="" are="" used="" for="" free-space="" communications="" for="" line="" of="" sight="" transmission.="" at="" slightly="" higher="" power,="" direct="" diode="" lasers="" are="" used="" to="" initiate="" ordinances.="" for="" even="" higher="" powers="" and="" long="" wavelengths,="" diode="" lasers="" can="" be="" used="" directly="" or="" to="" pump="" solid="" state="" lasers="" which="" disable="" incoming="" heat="" seeking="" missiles.="" at="" the="" highest="" power="" levels="" of="" 50-100kw,="" high="" energy="" solid="" state="" lasers="" for="" missile="" defense="" are="" being="" developed.="" these="" lasers="" use="">100kW of diode pump light per laser and are expected to be deployed by land, sea, and air in the years to come.

Another class of defense laser is those which are used to extract information from a target. At the low power end, for example, range finding lasers enable the user measure distance and illuminators enable the user to view unprecedented levels of detail. At higher power, remote sensing and LIDAR lasers allow the user to detect bio-chemical agents, clear air turbulence and other atmospheric conditions.This new class of direct diode rangefinders and compact LIDAR systems is based on QPC's proprietary high efficiency material design around the Eyesafe wavelength of 1550nm and unique high power single mode laser designs exceeding 1W CW.

A new class of non-lethal laser weapons is also enabled today withby QPC Lasers. These lasers use high brightness green light to warn targets at a distance that is far enough to allow escalation of force and even suppress a potential threat while decreasing the risk for potential collateral damage. QPC's visible laser product line, based on integrated diode wavelength stabilization technology, allows integration of compact and efficient green lasers on various platforms from rifles to airborne and ground vehicles.
