Question

Mention the number of photons emitted in Quantum Cascade Laser for the transition of
single electron​

Answer 1

Answer:

The quantum cascade laser is a special kind of semiconductor laser, usually emitting mid-infrared light. Such a laser operates on laser transitions not between different electronic bands but on intersubband transitions of a semiconductor structure.

Answer 2

Quantum Cascade Lasers (QCLs) are semiconductor lasers that emit in the mid- and long-wave infrared bands, and they're finding new uses in precision sensing, spectroscopy, medical, and military applications .

• Faster and more precise small trace element detectors and gas analyzers are replacing slower and larger FTIR, mass spectroscopy, and photothermal micro spectroscopy devices thanks to their wide tuning range and fast response time.
• In a diode laser, one electron creates one photon, resulting in increased laser gain. Mainly one photon is emitted in Quantum Cascade Laser for the transition of single electron.
