Can laser light cool semiconductors?

Laser cooling in semiconductors is theoretically investigated including arbitrary external efficiency and photon recycling. Experimental conditions needed to attain net cooling in GaAs are derived.

Laser Cutting Theory

A laser can be used for cutting by exposing material to the intense heat energy developed by its beam. If that heat input to the material is greater than that material's ability to reflect, conduct, or disperse the added energy, it will cause a sudden rise in temperature of the material at that point. If the temperature rise is substantial enough, the input heat is capable of initialising a hol...

LASER CUTTING PARAMETERS The laser cutting parameters are dependent on the beam characteristics, the cutting rate

The laser cutting parameters are dependent on the beam characteristics, the cutting rate required, the composition and thickness of the material to be cut, and the desired cut edge quality. The laser cutting process and cut quality depend upon the proper selection of laser and workpiece parameters. Deficiencies in cutting quality may be related to the slow process drifts and disturbances that a...

Modeling for Self-Optimization in Laser Cutting

Laser based cutting processes comprise a significant part of industrial manufacturing. To ensure a high level of cutting quality the process parameters have to be kept at the right values and within defined tolerances. In this context, the position of the laser beam focus is one of the most important parameters. However, due to thermal heating of optical elements the focal position shows a tran...

Fiber Laser for Micro Cutting of Metals

The fiber laser concept is proven technology for telecom applications where its single mode performance and reliability is essential. Newer generation diode-pumped fiber lasers are using pump diodes especially developed for telecom applications and therefore offer excellent controllability of the laser pulse length and pulse frequency. In recent years the output power of fiber lasers has increa...
