    The expansion of sparks produced in various gas mixtures by a helical TEA CO2laser of modest power (∼ 0.5 MW) has been examined using time-resolved photography and two-wavelength interferometry. The latter was accomplished with the aid of a synchronized ruby laser, the fundamental and second-harmonic frequencies of which illuminated a Mach-Zehnder interferometer. The interferogram...

    The coupled Maxwell-Schrodinger equations are used to describe propagation of a pulse in a nonlinear absorbing medium. The absorber is assumed to be comprised of a homogeneously broadened system of two-level atoms that are exactly resonant with the field. Numerical calculations have been performed for incident pulses of hyperbolic-secant shape and of duration that is long compared to the atomic ph... View full abstract»

  • Simultaneous two-wavelength HF lasers

    Publication Year: 1973 , Page(s): 1152 - 1154

    A technique for operating a tunable laser simultaneously at two wavelengths has been applied to the infrared HF chemical TEA laser. The two output beams are independently tunable, collinear, and have mutually perpendicular polarizations. Because of collisional coupling between the vibrational-rotational (V-R) levels, the effect of stimulated emission on one set of levels can strongly affect the ga... View full abstract»

    A CO-laser-pumped InSb CW spin-flip Raman laser has been operated in a permanent magnet (∼1500 G) incorporating a field gradient that permits frequency tuning by moving the magnet relative to the InSb sample. Output lines up to the fifth Stokes and the second anti-Stokes are observed. Real-time Doppler-limited absorption spectroscopy employing a small external modulation coil is demonstrated...

  • Possibility of light-pulse generation from junction lasers by the external magnetic field

    Publication Year: 1973 , Page(s): 1154 - 1155
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (576 KB)  

    The possibility of light-pulse generation from junction lasers due to inhomogeneous excitation by an external magnetic field is discussed on the basis of the repetitively Q -switching model. The pulsation takes place with suitable choices of the current and the magnetic field. The pulsewidth and period increase with the magnetic field. View full abstract»

    Experimental results on the first miniature Nd:YAG laser end-pumped by a single incoherent infrared-emitting diode are given. Laser operation was verified by measurements of relaxation oscillations, angular divergence, wavelength, and nonlinear output. In order to emit in the 0.81- μm pump band of Nd:YAG, the GaAs1-xPxdiode required cooling to 88 K (-185°C). Cooling... View full abstract»

    Broad-band acoustooptic modulators have been designed and developed for fiber optical-communication applications. The specific function of these modulators is to impress signal information, up to 50 Mb/s, on the CW emission of Nd:YAG lasers. View full abstract»

  • Determination of gain, saturation intensity, and internal losses of a laser using an intracavity rotatable reflector

    A novel method is devised to determine the small-signal gain, saturation intensity, and internal optical losses in the cavity of a homogeneously broadened laser with the help of an intracavity rotatable reflector used as a variable coupling-out mirror. These laser parameters have been determined for a CW CO2laser. View full abstract»

  • Role of helium in TEA CO2lasers

    The role of helium in TEA CO2lasers differs from that in low-pressure CO2lasers. TE CO2laser output is nearly proportional to the gain-bandwidth product, and, at a total pressure of 250 torr, it is independent of whether helium is present or not. Above 250 torr, the laser could not be operated without helium. View full abstract»
