A 20 W, Less-Than-1-kHz Linewidth Linearly Polarized All-Fiber Laser
Applied Sciences, 2018 We report a continuous-wave high-output power and narrow-linewidth all-fiber laser at 1550 nm with the master oscillator power amplifier (MOPA) configuration. An all-fiber distributed feedback seed laser was boosted by three cascaded fiber amplifiers. In

Prospects for a Millihertz-Linewidth Laser [PDF]
Physical Review Letters, 2009 We propose a new light source based on having alkaline-earth atoms in an optical lattice collectively emit photons on an ultranarrow clock transition into the mode of a high Q resonator. The resultant optical radiation has an extremely narrow linewidth in the mHz range, even smaller than that of the clock transition itself due to collective effects.

Linewidth and phase noise characteristics of DFB fibre lasers
, 2004 The anomalous linewidth behavior in a DFB fiber laser is investigated. It is shown that not only does the linewidth deviate drastically from the Schawlow-Townes linewidth formula by increasing with pump and laser power, but it also varies significantly ...
