A 1.55-μm solid-state laser source for DWDM applications

Frequency and Intensity Noise of Single Frequency Fiber Bragg Grating Lasers

“…We see that the 1/f noise level of the Nd:YAG laser is very similar to that of the fiber laser. A linewidth of 22 kHz has recently been reported for a bulk Er:Yb-doped glass laser [2]. The corresponding noise level ν rms estimated from (5) is indicated by a black diamond.…”

“…Some of the most accurate sources available today are ring-cavity Nd:YAG lasers [1], Er:Yb-doped bulk glass lasers [2], semiconductor distributed feedback (DFB) lasers [3,4], external cavity semiconductor lasers, and short cavity fiber Bragg grating lasers [5]. Compared to other sources, fiber Bragg grating lasers have the advantages of a compact in-fiber design, easy and accurate wavelength selection during production, a large potential wavelength taneous laser frequency.…”

Investigation of the coupling between pump amplitude noise and differential phase noise in an Er,Yb:glass two-polarization dual-frequency solid-state laser

“…Low phase-noise lasers are mandatory in many applications including telecommunications and lidar-radar [1][2][3][4]. The laser linewidth of rare-earth doped solid state lasers is known to be smaller than in semiconductor lasers, where it is spoiled by amplitude-to-phase coupling (AM/PM) due to the Henry factor α [5,6].…”
