How does a tunable diode laser work?
A tunable diode laser operates by utilizing a semiconductor diode as the gain medium to generate laser light. When an electric current is applied to the diode, it produces photons through a process called stimulated emission. The photons are then confined within the laser cavity, where they bounce back and forth between two mirrors, amplifying in intensity. By introducing a grating or other tuning element within the cavity, specific wavelengths of light can be selected and emitted by adjusting the current or temperature of the diode. This tunability allows researchers to precisely target desired wavelengths for spectroscopic analysis, making tunable diode lasers a versatile and powerful tool in scientific research and industrial applications.
