An Ultra-High-SMSR External-Cavity Diode Laser with a Wide Tunable Range around 1550 nm
In this paper, a widely tunable external cavity diode laser (ECDL) with an ultra-high side mode suppression ratio (SMSR) was fabricated. Three configurations were constructed to investigate the relationship between the grating features and the SMSR. When a 1200 grooves/mm grating with a first order...
