摘要： A projector with high safety is provided by directly shutting down the laser beam production when normal scanning of the laser beam is not carried out, thereby reducing exposure to the laser beam. For this purpose, the projector is provided with a laser beam source (10) that outputs a laser beam and modulates the laser beam in a beam form based on an image signal, a scanning unit (30) that scans the laser beam output by the laser beam source (10) at least in one-dimensional direction, a scan driving unit (50) that drive controls the scanning unit by a first force, a retaining unit (40) that stops and retains the scanning unit at a predetermined position by a second force, and a light shielding unit (70) that shields the laser beam from the scanning unit (30) that is retained by the retaining unit (40). The scan driving unit (50) releases the scanning unit (30) retained by the retaining unit (40), and drives it when the first force is larger than the second force. The retaining unit (40) stops and retains the scanning unit (30) at the predetermined position when the second force is larger than the first force.

摘要： The microoptical device has beam-parallelizing optics and a deflecting mirror configuration. The device converts a laser beam bundle, which is emitted by a laser diode strip structure or individual diode chips and which is comprised of a plurality of strip-shaped individual laser beams, into a rectangular or parallelogram-shaped laser beam bundle composed of parallelized strip-shaped individual laser beams arranged parallel next to one another. The beam-parallelizing optics may be a cylindrical lens, and the deflecting mirror configuration may be two rows of mirrors. The cylindrical lens and the rows of mirrors are preferably produced from a semiconductor material and they can therefore be produced cost effectively by means of methods used in semiconductor process engineering.

摘要： A shutter mechanism having a slide element coupled to a support base by a plurality of roller bearings journaled between opposing pairs of guide rods is disclosed. The slide element and support base have corresponding beam apertures in alignment when the shutter is in its open position. Angularly mounted on the slide, adjacent to the slide's beam aperture, is a UV reflective mirror. When the shutter is commended to close, an actuator forces the slide and support base apertures out of alignment, while simultaneously positioning the UV reflective mirror into the position previously occupied by the slide's aperture. A laser beam, previously being transmitted through the aligned apertures, will be reflected by the mirror to a beam stop as a diagnostic instrument mounted on the support base.

摘要： An optical beam steering device (10) incorporates a laser (12), three Brillouin shifters (22 to 26, 44 to 48, 54 to 58), a four wave mixing cell (40) and a low power beam steering device (62). The first shifter (22 to 26) and the mixing cell (40) contain TiCl.sub.4, and the other shifters (44 to 48, 54 to 58) contain 20% CCl.sub.4 /80% CS.sub.2. The first and third shifters (22 to 26, 54 to 58) frequency downshift the laser beam (16) by .delta..upsilon..sub.A and .delta..upsilon..sub.B respectively. Light (16') from the first shifter (22 to 26) is amplified and provides a first pump beam input to the mixing cell (40). It then passes to the second shifter (44 to 48), for frequency downshifting by .delta..upsilon..sub.B and returns as a second cell pump beam ( 16"). Light (18') from the third shifter (54 to 58) passes via the low power beam steering device (62) to the cell (40) as a weak input signal beam (18"). The cell (40) responds to the pump beams (16', 16") and signal beam (18") by generating a high power beam (68) which is a phase conjugate of the signal beam (18") and retraces part of its steered path.

摘要： The invention relates to lasers, and more particularly to solid state lasers such as neodymium on lithium niobate crystal lasers. The invention provides a structure with several juxtaposed optical waveguides (12) sufficiently close to each other laterally to be coupled laterally. In order to take into account the risks of inhomogeneity in the refractive indices or inaccuracies in the dimensions which would alter the distribution of the electromagnetic field of the propagation supermode in the coupled structure, it is proposed to act on the value of the index of propagation in each guide using an individual control (generally electrical). Because of the variation in index, individually controlled, phase differences in the laser wave between the different guides are produced and these phase differences react on the composition of the electromagnetic field defining the supermode. It is possible to go as far as modifying the directivity of the laser beam by this electrical control. The control is preferably achieved by electrodes (14) placed in the vicinity of each guide. The guides are made of an electro-optical material such as lithium niobate, and neodymium doping, for example, allows the laser effect to appear in the very interior of the guides.

摘要： Apparatus (20) for increasing the length of a laser pulse to reduce its peak power without substantial loss in the average power of the pulse. The apparatus (20) uses a White cell (10) having a plurality of optical delay paths (18a-18d) of successively increasing number of passes between the field mirror (13) and the objective mirrors (11 and 12). A pulse (26) from a laser (27) travels through a multi-leg reflective path (28) between a beam splitter (21) and a totally reflective mirror (24) to the laser output (37). The laser pulse (26) is also simultaneously injected through the beam splitter (21) to the input mirrors (14a-14d) of the optical delay paths (18a-18d). The pulses from the output mirrors (16a-16d) of the optical delay paths (18a-18d) go simultaneously to the laser output (37) and to the input mirrors ( 14b-14d) of the longer optical delay paths. The beam splitter (21) is 50% reflective and 50% transmissive to provide equal attenuation of all of the pulses at the laser output (37).

摘要： Multiple discharge gas laser apparatus. A compact apparatus for simultaneously or individually generating a plurality of laser output beams in a selected pattern suitable for marking objects, for communications, or for remote chemical sensing or other remote sensing applications, among other uses, where all of the electrodes providing lasing gas excitation are located in a single gas volume and share a single output coupler is described. In this manner, all of the output beams are parallel in far field, to the extent variations in mode structure permit, without the necessity of undertaking detailed optical adjustments. Moreover, the focal plane of the output laser radiation is insensitive to significant positional variation of focusing optics utilized to increase the intensity thereof for marking purposes. Electrodes can be utilized for more than one discharge; that is, the direction of the discharge can be selected to involve any adjacent electrode having opposite charge polarity.

摘要： A medical laser delivery system is disclosed which includes a laser generating a high power, pulsed, treatment beam. The beam is coupled to an optical fiber which is placed adjacent to a tissue site immersed in a fluid medium. The wavelength of the laser light and the energy of the pulses is selected so that the fluid medium will be quickly vaporized creating a vapor bubble around the end of the fiber. The end surface of the fiber is angled in a manner such that after the vapor bubble is formed, the laser output will be totally internally reflected at the end surface and be redirected out of the side of the fiber.
