Phase and Frequency Locking of Diode Lasers
Monday, August 11, 2025
The monochromatic property of laser light is certainly one of its key features. It explains why the emergence of the laser led to a renaissance of traditional fields like atomic and molecular spectroscopy and at the same time triggered the birth of new fields like quantum optics and quantum information processing. This monochromatic property is rooted in the fundamental working principle of the laser that always contains a frequency-selective element. Examples for these elements in the case of diode lasers include external resonators and gratings written into the semiconductor.
