TL;DR: A coherent laser radar system as mentioned in this paper includes a pulsed laser oscillating an oscillating laser beam which is split into two parts by an optical divider, and a first part of the two is transmitted as a transmitted beam via a beam splitter, and another part is supplied to a delay line via coupling optics and others to be delayed by a predetermined time as a local beam, and is incident onto an optical coupler.

11-mJ, 15-Hz single-frequency diode-pumped Q-switched Er, Yb:phosphate glass laser.
TL;DR: A single-frequency diode-pumped Q-switched Er, Yb:phosphate glass laser that oscillates at an eye-safe 1.54etam wavelength has been developed for use in coherent Doppler lidar.
Patent
Laser light source device and image display apparatus
TL;DR: In this paper, the authors present a controller for controlling driving of the laser light source by the laser driver in accordance with the detection signal, and the light collecting lens is disposed in a eccentric-rotated state so that an optical axis of the light-collecting lens has a tilt with respect to a central ray of a laser beam being incident on the light collector lens.
Journal ArticleDOI
Phase locking in a Nd:YVO_4 waveguide laser array using Talbot cavity
TL;DR: In this paper, phase-locking in a laser-diode-array-pumped Nd:YVO4 laser array (15 emitters) using a Talbot cavity was demonstrated.
