Description
The 1550nm 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 polarization operation options.
The 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. Integrated and highly responsive power monitoring circuitry continuously feeds back to optimize laser operation. 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.
