semiconductor laser

Scientific  

1. A solid-state laser constructed like a semiconductor diode. At the junction of anode and cathode, electrons and holes come together; when an electron falls into a hole, bandgap radiation is emitted, as in a light emitting diode. Semiconductor lasers are constructed so that the resulting light tends to stimulate other nearby pairs of electrons and holes to undergo the same process, emitting more light.

2. Also called diode laser laser diode

3. See more at laser

Example Sentences

To accomplish this, researchers use a semiconductor laser, which acts as a very steady flashlight.

From Science Daily

The light from the semiconductor laser flows through microscopic waveguides into extremely small cavities, where the beam is trapped.

From Science Daily

The other significant achievement is the hybrid system's ability to double the frequency of the light coming from the commercial semiconductor laser -- enabling a shift from the near-infrared spectrum to the visible light spectrum.

From Science Daily

"The basic constituents of such links, the optical fiber, semiconductor laser, optical modulator and photoreceiver, all place limits on the bandwidth and the accuracy of data transmission."

From Science Daily

Dr. Holonyak was working General Electric’s Advanced Semiconductor Laboratory in Syracuse, N.Y., when a chemist colleague was working toward realizing a semiconductor laser that used invisible infrared light.
