    Several stable oligo-mode spectra of a CW dye laser were recorded with the aid of an optical spectrum analyzer (scannable Fabry-Perot) giving Fourier transforms of the light field. Simultaneously the total intensity was measured with a fast photodiode and analyzed for beat signals with an RF spectrum analyzer. The spectra observed can be explained consistently in terms of a kinematic model postula... View full abstract»

    We have successfully operated a CuCl laser in a metal tube in a hollow-cathode configuration. An average output of 400 mW was obtained with 0.06 percent "wall plug" efficiency. Excitation was by pulse burst with a repetition rate of 1-15 kHz within the burst. Despite the use of an unsealed vacuum system and cold windows the laser was operated for more than 300 h on a single charge of CuCl. The hol... View full abstract»

    CO2channel waveguide lasers have been constructed using boron nitride. This hot-pressed, smooth, easily machinable ceramic has high thermal conductivity and extremely low thermal expansion. These properties make it highly suitable for constructing compact, efficient, amplitude stable, tunable low-power lasers. View full abstract»

    Coupling coefficient calculations of the type originally published for gallium arsenide distributed feedback (DFB) lasers are here extended to the lead-tin telluride based family of devices. Specific calculations of the coupling coefficient as a function of active region and grating dimensions are presented for PbTe/Pb1-xSnxTe/PbTe devices, ... View full abstract»

  • Optically pumped submillimeter wave laser with Michelson interferometric output coupling

    Publication Year: 1977 , Page(s): 30 - 33

    We report the performance of an optically pumped submillimeter wave laser incorporating a Michelson interferometric output coupler consisting of three mirrors and a metal mesh beam splitter. 10.33-μm radiation from a pulsed CO2TEA laser was used to pump NH3for generating submillimeter wave radiation at 281 μm. Optimum output was achieved by coupling out 59 percent o... View full abstract»

    The performance of a CO laser having electrical excitation by a continuously operating, self-sustained glow discharge in a high-pressure gas mixture followed by a supersonic expansion to the cavity region has been studied. A threshold for lasing was found which corresponded to 0.035 eV of input energy per CO molecule. Beyond this, nearly 15 percent of the additional energy was extracted by the res...

  • Suppression of transverse modes of a CW CO2laser by cavity length control

    Publication Year: 1977 , Page(s): 29 - 30

    The described technique of transverse mode control makes use of the small transition linewidths of the CW CO2laser. The laser medium itself is used for spectral discrimination. The method was tested and found to be superior to the usual technique of using an intracavity iris. View full abstract»

    Experimental results are reported on the room-temperature operation of Nd:YAG lasers end pumped with an LED. The radiation from a 10-percent-efficient 0.46-mm-diam domed LED was coupled to the end of a 0.46-mm-diam × 5.0-mm-long laser rod with a large hemispherical reflector. At 20°C, a multimode laser power of 0.25 mW was obtained at an LED current of 250 mA. By measuring the variation ... View full abstract»
