1550nm polarization maintaining pulsed Erbium fiber laser series are especially designed and developed for LIDAR and remote sensing applications. These lasers are "eye safe", and have broad range of pulse widths, repetition frequency, peak power and energy per pulse as well as linear or random operation options.
The polarization maintaining pulsed Erbium fiber laser is based on MOPA configuration (Master Oscillator Power Amplifier) that uses laser pulse generation, triggering, gating and ASE suppression technology. This configuration allows laser pulse characteristics to be easily controlled and adjusted for customized applications. This laser module features effective management interface for users to access, monitor and adjust key operating parameters. User-friendly RS-232 interface ensures reliable connectivity with customer's control system.

polarization-maintaining:
In fiber laser, polarization-maintaining optical fiber (PMF or PM fiber) is a single-mode optical fiber in which linearly polarized light, if properly launched into the fiber, maintains a linear polarization during propagation, exiting the fiber in a specific linear polarization state; there is little or no cross-coupling of optical power between the two polarization modes. Such fiber is used in special applications where preserving polarization is essential.
