Other users also ask the following questions:
1.How does tunable laser source work?
A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. While all laser gain media allow small shifts in output wavelength, only a few types of lasers allow continuous tuning over a significant wavelength range.
2.What does it mean to tune a laser?
If a laser is tunable, its wavelength can be changed within a defined range in a controlled manner. In some cases, this tuning range is in excess of several hundred nanometers. The wavelength resolution differs from system to system.
