摘要： A frequency agile optical radar system including a frequency agile laser rce coupled with an extra-cavity dispersive element in such a manner as to radiate into space specific optical frequencies correlated with specific elevation angles measured from the horizontal. Laser radiation reflected from an object in space is detected by a staring detector system and the wavelength of the reflected optical energy determined therefrom. The elevation angle of the object in space is correlated with the optical frequency determination and coupled together with target range and aximuth angle so that the position and range to an object in space may be determined.

摘要： A liquid mirror for high energy lasers. A working liquid such as mercury, used as the reflecting surface for laser light. Dielectric enhanced reflecting techniques can be used to increase significantly the amount of reflection from the working liquid. The liquid is contained in a pressure cell behind a transparent optical flat. By varying the pressure cell of the liquid, compensation for the aberration caused by heat absorption can be made. These same pressure changes can be used to correct for laser beam wavefront distortions produced elsewhere in the laser, director or atmosphere.

摘要： A multiple pulse laser from a single resonant cavity. An acousto-optic cells used to modulate coherent light from a lasing element. Either multiple chirp signals or a masked mirror are used to provide distinct pulses of light. Through proper choice of materials for the acousto-optic cell and use of divergent optics, a higher power level is obtained. Use of a multi-tapped delay line permits a shorter period between pulses due to the linear superposition principle. When the mask embodiment is used, the acousto-optic cell focuses light which scans across the mask. Whenever the focused light passes through the mask, lasing occurs which generates an output pulse.
