MUSES-C is a sample return mission of a near-earth asteroid. The MUSES-C spacecraft rendezvous and touches down an asteroid. In order to approach safely, it has a LIDAR system with the range covering from 50 m to 50 km. The range accuracy at 50 km was less than 10 m. The LIDAR uses a diode pumped Nd:YAG laser with l2mJ output energy for ranging. The prototype-model of the LIDAR was developed and it has been testing to prove performance for MUSES-C. The prototype-model of the laser satisfied all of the required specifications for MUSES-C. Also, the laser realized the weight fewer than 300g with Mg alloy for frame and glue fixation of optics.
