Er-doped fiber amplifier / laser 1530-1598 nm

The erbium-doped single-frequency fiber amplifier can be divided into two versions according to different output power.  The low-power version has a maximum output power of 15W with extremely low noise and RIN below -140 dBc/Hz (100 kHz).  The high power version has a maximum output of 40W.  It can be used for remote interferometry, coherent communication, and atomic physics after frequency doubling. The amplifier remains mode-hopping-free and stable under wide temperature variation and high mechanical vibration, which is great for frequency locking. The fiber laser is an optimal solution for applications in outdoor harsh conditions.
