Paper Abstract

Recently, we have developed the high output power laser amplifier using Er,Yb:glass planar waveguide in order to increase the measurable range of our 1.5 μm coherent Doppler LIDAR (CDL). In this paper, we introduce this development and demonstration of a long range wind sensing using the developed system. The transmitted pulse has a peak power of 2.4 kW and a width of 580 ns (i.e. pulse energy of 1.4 mJ) with a pulse repetition frequency of 4 kHz, in addition to a nearly diffraction limited beam quality. With this laser amplifier, we demonstrate the measurable range of more than 30 km. According to our own research, this is the longest measurable range demonstration for wind sensing CDLs.
