    Using quasi-CW sinusoidally modulated excitation from a 0.8-μm-wavelength laser diode, we have obtained driven spiking oscillations in miniature, high-Nd-concentration room-temperature lasers of NdP5O14, and NdAl3(BO3)4. With modulation indices of 0.25 or less, peak-power enhancements of 11 (at 35 kHz) and 7 (at 124 kHz), respectively, ha... View full abstract»

    This paper investigates some of the properties of continuous wave (CW) (AlGa)As-GaAs injection lasers with Al in the active region. The active region gain at threshold g th is estimated as a function of Al concentration in the active region. The basic configuration is a five-layer structure with GaAs as the two outer regions; the center region is Al... View full abstract»

  • Computer solution for the traveling-wave-excited N2laser

    Publication Year: 1976, Page(s):204 - 207

    A computer solution is presented for the nitrogen laser excited by a longitudinal relativistic electron beam. The solution demonstrates efficient extraction by amplified spontaneous emission, and preferential radiation parallel to the electron beam, caused by the traveling-wave nature of excitation. These observations tend to validate approximations used to calculate extraction in an earlier study... View full abstract»

  • Parameter ranges for CW passive mode locking

    CW passive mode locking of a homogeneously broadened laser is considered. In the coordinate plane, whose abscissa is proportional to the small-signal saturable absorber loading, and whose ordinate is proportional to the small-signal gain, the following regimes are laid out: 1) steady-state single-pulse mode-locking solutions; 2) stability against relaxation oscillations; 3) self-starting of mode l...

    A pulsed CO2-pumped external cavity spin-flip laser has been operated with the output frequency governed to a large extent by the Fabry-Perot (FP) modes of resonant output couplers. An output spectral width of 0.027 ± 0.003 cm-1has been attained. View full abstract»

  • Laser frequency doubling in the presence of small-scale beam breakup

    Frequency multiplication of intense laser pulses in narrow acceptance angle crystals is commonly accomplished with large conversion efficiency. However, the conversion efficiency can be seriously affected by degradation of the laser pulse, such as occurs when small-scale intensity fluctuations exponentiate due to nonlinear refractive effects within the laser. We present evidence that beam breakup ... View full abstract»

    The design and performance of a self-heated metal-vapor laser utilizing copper, gold, and copper plus gold as active laser materials are described. A total average power of 17 mW at a pulse-repetition rate of 1.7 kHz was obtained simultaneously at 5106 Å (green), 5782 Å (yellow), and 6278 Å (red). The purpose of the research reported here was to obtain multiple-wavelength laser oper... View full abstract»

  • Suppression of the relaxation oscillation in the modulated output of semiconductor lasers

    Practical rates of direct pulse modulation of semiconductor lasers have so far been limited to below several hundred megahertz, owing to serious distortion in the output signal caused by the relaxation oscillation of the light intensity. Based on theoretical analysis of the dynamic properties of lasing under constant injection of external radiation into the cavity modes, light injection is propose... View full abstract»

  • Influence of spatial hole burning on the output power of a CW dye ring laser

    Publication Year: 1976, Page(s):207 - 209

    The output power of a single-mode CW dye ring laser can be enhanced by 50 percent by changing over from standing-wave (SW) operation to traveling-wave (TW) operation. This effect is attributed to smoothing out the SW pattern in the active medium, which gives rise to spatial inhomogeneities of the inversion. View full abstract»

    Double-heterostructure (DH) diode lasers with a thin Ga1-xAlxAs layer between the active GaAs region and the GaAs substrate or superstrate are analyzed. In these devices power flows through the thin Ga1-xAlxAs layer and is radiated into the substrate or superstrate. Three methods for computing the laser thresholds are developed and compared. The first is... View full abstract»

    Based on measurements of the transient voltage across the cavity of a transversely excited N2laser an equivalent circuit is developed which provides better understanding of the contribution of all individual components to maximum peak power. Consideration of the design criteria established guarantees about one million light pulses with more than 1 MW from simple high-efficiency construc... View full abstract»
