Based on Erbium-doped fiber amplifier technique, Precilasers can provide amplifier that cover 1525-1625nm range, to maxium power of 40W， and keeping very low phase noise and intensity noise.
Based on Erbium-doped fiber amplifier technique, Precilasers can provide amplifier that cover 1525-1625nm range, to maxium power of 40W， and keeping very low phase noise and intensity noise.
Precilaser’s 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.
Features:
● Narrow Linewidth(<1 kHz)
● Support Seed built-in, Tunable
● Extremely Low Intensity Noise (RIN -140 dBc/Hz @100 kHz)
● Excellent Beam Quantity(M² <1.1)
● Seed Power off Protection System
