摘要： Heretofore, if the beam size of the resonance mode is made small in a long resonator length, there arises a problem that the operation of the laser resonator becomes easy to be unstable and hence the adjustment thereof becomes difficult. A laser resonance includes: a laser material; a telescope for magnifying a laser beam which has been made incident from the laser material and for reducing a laser beam which has been made incident from the side opposite thereto; a flat reflecting mirror for reflecting the laser beam which has been made incident from said telescope; a telescope for magnifying the laser beam which has been reflected by the flat reflecting mirror to be reduced by the telescope and to be amplified by the laser material to be made incident thereto; and a flat reflecting mirror for reflecting the laser beam which has been made incident from the telescope. The telescope having suitable magnification is selected for the resonator length, whereby the beam size of the resonance mode at the center of the resonator can be arbitrarily adjusted and the stable resonator which has the small beam size with the long resonator length can be constructed.

摘要： A coherent laser radar system includes a pulsed laser oscillating a pulsed laser beam which is split into two parts by an optical divider. A first part of the two is transmitted as a transmitted beam via a beam splitter. A second part is supplied to a delay line via a coupling optics and others to be delayed by a predetermined time as a local beam, and is incident onto an optical coupler. The received beam from the target is incident onto the optical coupler via a scanning optics and so on. A photodetector carries out the coherent detection of the light beam coupled by the optical coupler. A signal processor computes a target velocity and the like from a signal generated by the detection and converted into a digital signal by an A/D converter. This makes it possible to solve a problem of a conventional system in that the system configuration is complicated and expensive.
