1540~1560nm Single-Frequency Pulsed Erbium-doped Fiber Amplifier Module Type EDFA-SFPL-1550-50-SM-M
The single-frequency pulse erbium-doped fiber amplifier is a fiber amplifier dedicated to narrow linewidth single-frequency nanosecond pulses. The spectral linewidth of the input laser pulse can be as low as the kHz level. It can effectively suppress nonlinear effects while achieving high pulse energy output. Mode or polarization maintaining fiber output. Can be used in distributed sensing, Doppler lidar and other applications.

*Note1:
ACC mode - automatic current control: The EDFA pumping operating current is set by the user and automatically locked by the EDFA to achieve a constant pumping current. When the input optical power fluctuates, the output power will also fluctuate accordingly, which is suitable for all EDFA models.
