Single-longitudinal mode (slm) laser, английский
A laser, usually distributed feedback (dfb) type, where the spectral width is the width at the 20 db down points divided by 6.07
Tunable laser, английский
- A laser that can change its wavelength. applications include research, otdrs, and for protection in transmission systems
- A laser system that can be "tuned" to emit laser light over a continuous range of wavelengths or frequencies.
