Abstract

A homemade PQ:PMMA VBG was fabricated and characterized with a diffraction efficiency of about 8%. Mounting on an annular piezo-transducer, this VBG served as a narrow band feedback mirror of a 1060 nm external cavity diode laser (ECDL), which achieved a single longitudinal mode and frequency-tunable operation. With the laser source, an FMCW LiDAR system was demonstrated and successfully measuring target distance within 8.5 m.
