The laser radar system includes: a laser light source for generating pulse laser light; a scanner for transmitting a transmitting pulse toward a target while two-dimensionally scanning a pencil-shaped transmitting beam, and outputting scan angle information; a lens of the receiver for receiving received light which has arrived; a high aspect photo detector array for converting the received light into a received signal and outputting the received signal; a transimpedance amplifier array for amplifying the received signal; an adder circuit for adding the received signal from each element of the transimpedance amplifier array; a distance detecting circuit for measuring a light round-trip time to the target of an output signal from the adder circuit; and a signal processing unit for causing the scanner to perform a two-dimensional scanning operation in association with the scan angle information, to thereby determine distances to multiple points on the target based on the light round-trip time and a speed of light and measure a three-dimensional shape of the target.

    摘要： A plane waveguide type laser according to the present invention includes: a plate-shaped laser medium (5); a semiconductor laser (1) which causes excitation light to enter an end surface (5a) of the laser medium (5); first and second claddings (4a and 4b) which are bonded to lower and upper surfaces of the laser medium (5), respectively, to form a waveguide in a vertical direction; a comb heat sink (2) bonded to a lower surface of the first cladding (4a); and thermal lens producing means (20) bonded to an upper surface of the second cladding (4b). In this structure, laser oscillation in the vertical direction is performed in a waveguide mode of the laser medium (5), and the thermal lens producing means (20) forms a periodic lens effect in the laser medium (5) to perform laser oscillation in a lateral direction in a plurality of resonant modes. Therefore, a resonator having a small round-trip loss may be formed without depending on a size of a thermal lens produced by excitation, and hence a rising characteristic of a pulse operation or a CW operation may be smoothed to obtain high-power stable output.
