Abstract: A semiconductor laser produces infrared radiation suitable for jamming a heat seeking missile, wherein a wavelength of the radiation is in a range of 2-5 microns, and the laser has a semiconductor lasing medium of Pb1-xSexPb1-xSnxSe or Ga0.84In0.16As0.14Sb0.86. These materials can be doped to provide a p/n junction, wherein the laser is excitable by electric current passing through the p/n junction. The third one of these materials can be constructed also as a uniform undoped slab which is excitable optically. Cooling of the lasing medium is accomplished by use of a lithium heat sink thermally coupled to the lasing medium by a diamond thermal diffuser which conducts heat from the relatively small region of the laser to spread out the thermal energy along a relatively large surface of the heat sink. Modulation circuitry is connected to the excitation apparatus to provide a pulse train of the radiation.

Abstract: A repetition rate (pulse) multiplier includes one or more beam splitters and prisms forming one or more ring cavities with different optical path lengths that delay parts of the energy of each pulse. A series of input laser pulses circulate in the ring cavities and part of the energy of each pulse leaves the system after traversing the shorter cavity path, while another part of the energy leaves the system after traversing the longer cavity path, and/or a combination of both cavity paths. By proper choice of the ring cavity optical path length, the repetition rate of an output series of laser pulses can be made to be a multiple of the input repetition rate. The relative energies of the output pulses can be controlled by choosing the transmission and reflection coefficients of the beam splitters. Some embodiments generate a time-averaged output beam profile that is substantially flat in one dimension.

Abstract: A generation unit generates adjustment information to adjust a first clock indicating a timing of illumination of a laser beam to scan on a screen, based on a scanning position to be scanned by the laser beam. On the basis of the adjustment information, adjustment unit adjusts the first clock to a second clock different from the first clock. Then, in synchronization with the second clock, the laser beam is allowed to illuminate as a pixel. This may be applicable to a projection apparatus for projecting an image on the screen, for example.

Abstract: A pulse multiplier includes a beam splitter and one or more mirrors. The beam splitter receives a series of input laser pulses and directs part of the energy of each pulse into a ring cavity. After circulating around the ring cavity, part of the pulse energy leaves the ring cavity through the beam splitter and part of the energy is recirculated. By selecting the ring cavity optical path length, the repetition rate of an output series of laser pulses can be made to be a multiple of the input repetition rate. The relative energies of the output pulses can be controlled by choosing the transmission and reflection coefficients of the beam splitter. This pulse multiplier can inexpensively reduce the peak power per pulse while increasing the number of pulses per second with minimal total power loss.
