Overview
Quantum cascade laser (EC-QCL) is a tunable shock wavelength laser that can undergo controlled stepwise changes in wavelength output. This enables the application of lasers in a wide range of spectroscopic applications. The $r $n quantum cascade laser (QCL) uses specially grown semiconductor chips as the gain medium of the laser. The energy of semiconductor chips is provided by external power. The optical cavity of the $r $n laser contains reflective surfaces that repeatedly reflect the laser beam through the gain medium. Every time it passes through the gain medium, the laser beam gains more energy.

Principle Introduction:
Quantum cascade laser （QCL）Use specially grown semiconductor chips as the gain medium for lasers. The energy of semiconductor chips is provided by external power.
The optical cavity of a laser contains reflective surfaces that repeatedly reflect the laser beam through a gain medium. Every time it passes through the gain medium, the laser beam gains more energy.
By integratingQCLChip integration into external cavity（EC）More precise wavelength control can be achieved through the use of at least one external cavityQCLThe reflective surface outside the chip serves as a part of the optical cavity.
This allows the incorporation of diffraction gratings into the optical cavity to provide wavelength selection and a wide tuning range.
