Description
The PEFA-LP-C-PM (PEFA-EOLA) series is a range of 1.5µm pulsed fiber amplifiers specially designed for Doppler heterodyne LIDAR systems, delivering Fourier transform limited pulses with high energy and high peak power. Shorter pulse duration with high peak power are well suited to high spatial resolution middle range systems whereas longer pulses with high energy are well suited for long range applications. Thanks to innovative optical designs, the amplifiers can emit up to 220µJ energy and up to 900W peak power with a linear polarization and an excellent output beam quality (diffraction limited or M2 <1.1 to 1.5 depending on peak power). This product range is ideal for various wind measurement applications such as windfarm optimization and wind hazard and wake vortices monitoring. High pulse repetition frequency (maximum 10 to 20 kHz depending on versions) allows speckle averaging and higher measurements rate. The rugged modules can work in the most stringent environments 24 hours/24. Lumibird provides numerous of PEFA-LP-C-PM (PEFA-EOLA) amplifiers which operates continuously under vibrations, shocks and strong temperature variations. Furthermore, the OEMs incorporate a microcontroller for internal controls, alarms, and RS232 communications making the amplifier compatible with all systems. An output circulator can be implemented into the module in order to collect the backscattered light for the Heterodyne measurement.
