    Spectral data for argon, krypton, xenon, and neon flashlamps are presented for the region of lamp operation in which the line radiation makes up a substantial portion of the total radiant energy. The spectral charateristics are presented in terms of both power flux and emitted quanta per unit area per second, the latter being appropriate for the characterization of illumination and laser pumping e...

  • Photon echoes and combination tones - A comparison between their polarization dependence

    Publication Year: 1969 , Page(s): 246 - 249

    The effects of level degeneracy on the polarization dependence of photon echoes and of combination tones in gases are compared. A remarkable similarity in behavior is found to exists, with quantitative agreement in the case of several simple transitions. By analogy, the echo behavior for elliptically polarized input pulses is suggested. View full abstract»

    A steady-state solution describing \Pi -pulse propagation in a homogeneously broadened laser amplifier embedded in a dispersive lossy host is found. For a given model of dispersion, the solution satisfies exactly the second-order wave equation together with the equations of motion for the density matrix of the two-level resonant system. The salient feature of... View full abstract»

  • Role of optical flux and of current density in gradual degradation of GaAs injection lasers

    A GaAs dual-diode laser structure was used to give electrical control of the laser threshold and so permit separate study of the effect of optical flux on gradual degradation. At a given current density, degradation occurs under nonlasing conditions at about the same rate as under normal lasing conditions. The degradation rate is a superlinear function of current density. Degradation is an erratic... View full abstract»

    A comparison of rare-gas flashlamps for pumping YAG: Nd3+and neodymium-doped glass, which shows krypton lamps to be superior to xenon under certain circumstances, is presented. The emission spectra of argon have the best match to the neodymium absorption spectra, but argon lamps suffer from low radiative efficiency except at very high pressures. A detailed analysis of theoretical laser ... View full abstract»

    Details of experimental results on higher order phase-locking phenomena of a He-Ne laser with a fixed cavity length and a fixed position of the laser tube in the cavity are presented. Two methods have been used in the experiments in order to obtain high bit-rate optical pulses. In one method modified Michelson-type resonators and a three-mirror Fabry-Perot resonator are utilized to suppress the os... View full abstract»

    A potassium-mercury lamp in a sapphire envelope was constructed. Under the proper conditions of pressure and temperature the potassium resonance lines radiate efficiently at the infrared absorption lines of Nd3+in YAG. Spectral tests indicate that a threefold improvement in pumping efficiency should be obtained compared with a tungsten filament lamp. CW room-temperature laser tests resu... View full abstract»
