摘要： A device is provided for the prolonged illumination of an object from an initial transitory illumination. This device comprises a laser whose cavity is closed by two total reflection mirrors; in the path of the intra-cavity radiation is disposed a photoexcitable interaction medium with index variation in the volume of which the transitory signal wave coming from the object and the intra-cavity radiation interfere; this interference generates in real time an index strata grating which diffracts a complex conjugate wave of the signal wave which returns to the object.

摘要： A laser system for medical applications has at least two lasers and a movable concave reflector. The lasers are capable of generating beams of coherent electromagnetic radiation. One of the beams, an aiming beam, is aligned to impinge the reflector, to reflect therefrom and to impinge a biological specimen. The reflector is moved until the beam is aligned to impinge the desired position. The reflector is held stationary and the second beam is generated. The second beam is also aligned to impinge the reflector to reflect therefrom and to impinge the same desired position as that impinged by the first beam.

摘要： A multistaged Stokes injected Raman capillary waveguide amplifier for providing a high gain Stokes output signal. The amplifier uses a plurality of optically coupled capillary waveguide amplifiers and one or more regenerative amplifiers to increase Stokes gain to a level sufficient for power amplification. Power amplification is provided by a multifocused Raman gain cell or a large diameter capillary waveguide. An external source of CO.sub.2 laser radiation can be injected into each of the capillary waveguide amplifier stages to increase Raman gain. Devices for injecting external sources of CO.sub.2 radiation include: dichroic mirrors, prisms, gratings and Ge Brewster plates. Alternatively, the CO.sub.2 input radiation to the first stage can be coupled and amplified between successive stages.

摘要： A manual manipulator mechanism for a surgical or industrial laser employs reflecting mirrors 1, 3 each rotatable about two perpendicular axes, to thereby reduce the total number of mirrors required and simplify the overall mechanism. Optical alignment is maintained by a linkage arm and yoke arrangement which is fully rotatable about a first axis, and which causes the controlled mirror to pivot through an angle one-half as much as the laser beam outlet tube 13 pivots about a second axis. The linkage arms may be replaced by a gear or friction wheel mechanism.

摘要： An image amplifying multi-mode laser with image forming elements in the cavity and with a saturable absorber film at the focal plane in the cavity. Radiation from each point of an image is focused on the saturable absorber film so as to enter a distinct mode of the multi-mode laser. Pump power and saturable absorber film density are jointly adjusted so that a mode of the laser oscillates if and only if the intensity of the radiation from the corresponding image point exceeds a given threshold value. The energy emitted from the bistable laser oscillations constitutes the output. The multi-mode threshold laser is useful for image contrast enhancement, applying a threshold operation in optical information processing, selection of the maximum point of optical matched filter output images and as a naturally formed collection of optical logic elements. Embodiments are disclosed in retro-reflector cavities having both traveling and standing wave modes.

摘要： Diffracted leaky optical waves are coupled out of a thin film optical waveguide device having one surface which is periodically thickness-modulated or corrugated to form an optical diffraction grating. The waveguide device is constructed such that the average thickness of the waveguide in the complex refractive index of the waveguide or one of the layers surrounding the waveguide is varied when an external power source applied to the device is varied and thereby, a parameter of the leaky wave in accordance with the variable power source. In one embodiment, the waveguide is made of light amplifying material which is suitably excited to produce lasing action and cause an optical wave to propagate in the waveguide. The variable parameter in this case is the wavelength of the leaky wave, and the leaky wave is always normal to the plane of the diffraction grating. Consequently, a tunable laser is provided. In a second embodiment, no lasing occurs, but instead, an external light source is used to cause an optical wave to propagate in the waveguide. The parameter which is varied is the angle between the leaky wave and the normal to the diffraction grating, the wavelength of the leaky wave remaining constant.
