    A laser-triggered spark gap using a liquid dielectric has been investigated. A parametric study has been performed relating the delay and jitter characteristics of the switch to the laser parameters. Delay times of less than 30 ns were observed with apparent subnanosecend jitter times. View full abstract»

    The current noise of GaAs laser diodes in the luminescence mode has been measured at frequencies between 0.47 kHz and 1.5 MHz. A1/fbehavior is found at relatively lower frequencies. In the investigated frequency range, the noise level is considerably higher than2cdotecdotIcdotDeltaf. View full abstract»

    The static and dynamic behavior of a single-mode 4-level solid-state laser has been studied both theoretically and experimentally. In the theoretical section, the usual rate equations are modified in order to take into account the spatial variation of the inverted population due to the cavity field. These theoretical results have been verified with the help of a CW Nd-YAG laser. The experimental results on the output power and on the transient behavior are in good agreement with the theory within the accuracy of the experimental results (∼ 15 percent). View full abstract»

    An optical frequency shifter making use of the electro-optic effect in LiNbO3was built to shift the Fourier spectrum of a mode-locked He-Ne laser; the shift was continuously adjustable from -45 GHz to +45 GHz about the central optical frequency of 473.61 THz. Shifted Fourier spectra recorded with a scanning Fabry-Perot interferometer were found to be in excellent agreement with theory. View full abstract»

    Using a dispersive prism, the room temperature YAlG : Nd laser has been made to oscillate CW on a total of seven4F_{3/2} rightarrow4I_{11/2}transitions ranging in wavelength from 1.0519 μm to 1.1226 μm and a single4F_{3/2} rightarrow4I_{13/2}transition at 1.319 μm. View full abstract»

  • Stabilized single-frequency output from a long ring laser

    Page(s): 485 - 490

    A technique for obtaining high-power single-frequency output from a long ring laser is described and demonstrated. A double feedback system is discussed, which stabilizes the laser frequency with respect to the center of the atomic gain curve. Experiments are reported which demonstrate the existence of a narrow atomic-line-center discriminant. The extension of this technique to dc-excited ion lasers is discussed. View full abstract»

    Since the fields inside a laser cavity are much higher than the external fields, an analysis of a parametric oscillator with the nonlinear crystal internal to the laser is performed. Using self-consistency equations as the starting point, the equations of motion of such an oscillator are derived. Depending on various cavity, pumping, and nonlinearity parameters, these lead to several types of oscillation with distinctly different operating characteristics: (1) efficient parametric oscillation similar to that of previous analyses; (2) inefficient parametric oscillation resulting from the fact that the nonlinear interaction drives the phases rather than the amplitudes of the signal, idler, and pump; and (3) a pulsing output from the oscillator with repetitive pulses of the signal and idler. A stability analysis of these various regions shows that they are mutually exclusive and can be experimentally chosen by changing the laser gain, the oscillator output coupling, or the strength of the nonlinear interaction. It is shown that the internal oscillator efficiency rapidly approaches the Manley-Rowe limit, as the available pump power becomes several times greater than that required for threshold. The efficiency of an external oscillator having a triply resonant optical cavity is found to be generally less than that of the corresponding internal oscillator. View full abstract»
