2-μm double-pulse single-frequency Tm:fiber laser pumped Ho:YLF laser for a space-borne CO 2 lidar

Résumé

In the framework of space-borne CO2 lidar development, the transmitter is a critical unit. We report on the development and the assessment of performances of a 2-µm single-frequency thulium fiber laser pumped Q-switched Ho:YLF laser. To fulfill the requirements of space-based operation, a master oscillator power amplifier architecture has been chosen, and the oscillator works in double-pulse operation. The transmitter can generate a single-mode dual wavelength emission “ON” and “OFF” around the R30e line of the 20013?00001 band of CO212. It delivers a pair of OFF-ON pulses with 12 mJ and 42 mJ energy, respectively, at a pulse repetition frequency of 303.5 Hz. The pulse energy and central frequency stabilities are especially documented as well as pulse duration, polarization, overall efficiency, beam quality, pointing stability, and spectral purity. The possible limitations by light-induced damage or radiation-induced attenuation on the laser performances are also evaluated.
