Seeding of a Titanium Sapphire oscillator by a vertical‐cavity surface‐emitting Laser in the nanosecond range
Applied Physics Letters, 1994Co-Authors: Yann Boucher, Patrick Georges, Alain Brun, Jean-paul Pocholle, Michel PapuchonAbstract:A GaAs/AlGaAs vertical‐cavity surface‐emitting Laser was used to seed a Titanium‐Sapphire Laser oscillator. Both Lasers were pumped synchronously by the same frequency‐doubled Nd:YAG Laser in the nanosecond range. Even at low injection level, we obtained a strong narrowing of the emission spectrum of the oscillator (from 30 to 1 nm), as well as its tunability over a broad range of wavelengths (from 775 to 805 nm).

the 3ν1 ν3 vibrational overtone spectrum of 13ch4
Principles and Practice of Constraint Programming, 1995Co-Authors: Kirk Boraas, James P. ReillyAbstract:Abstract The 3 ν 1 + ν 3 vibrational overtone spectrum of 13 CH 4 is recorded under Doppler-limited resolution conditions using a Titanium Sapphire Laser-based photoacoustic spectrometer. Data at two temperatures, 100 and 293 K, are presented. The observed spectral congestion is qualitatively similar to that observed for 12 CH 4 , but the detailed ro-vibrational structure of the two isotope variants is completely different. The data reflect the complicating influences of tetrahedral fine structure and vibrational state mixing.

A dye Laser-based amplifier for a CW mode-locked Titanium Sapphire Laser and its use in the production of tunable ultraviolet light pulses
Optics Communications, 1995Co-Authors: John P. Lucia, James P. ReillyAbstract:Abstract A multi-staged dye amplifier pumped by the second harmonic of a Q -switched Nd:YAG Laser is used to amplify the output pulses from a commercial cw mode-locked Titanium Sapphire Laser. The amplified light is frequency-doubled and the resulting blue pulses pass through a second dye amplifier pumped by the third harmonic of the Q -switched Laser. The blue and red light beams are then frequency summed to produce tunable ultraviolet light. Their cross-correlation indicates that the temporal width of the uv pulses is about five picoseconds.

Generation of continuous-wave terahertz radiation using a two-mode Titanium Sapphire Laser containing an intracavity Fabry–Perot etalon
Journal of Applied Physics, 2005Co-Authors: Michael R. Stone, Mira Naftaly, Robert E. Miles, Iván Cámara Mayorga, A. Malcoci, Martin MikulicsAbstract:Continuous-wave terahertz (THz) radiation was generated by photomixing two modes of a Titanium Sapphire Laser. The Laser was induced to oscillate on two modes by placing a Fabry–Perot etalon in the Laser resonator. The frequency of terahertz radiation, which was equal to the difference frequency of the two modes, was varied by adjusting the free spectral range (FSR) of the etalon. Photomixing was performed by logarithmic spiral antennas fabricated on low-temperature-grown GaAs; and the emitted THz radiation was characterized. The THz power, measured by a Golay cell, was 1μW at 0.3THz and 0.7μW at 0.5THz. The THz frequency, as determined by a Fourier transform interferometer, was seen to correspond to the etalon FSR. The current-voltage characteristics of photomixers were also determined, and photocurrent modulation was observed by the autocorrelation of the Laser beam.

Laser emission of Nd:ASL at 900 nm
Advanced Solid-State Lasers, 2002Co-Authors: Gérard Aka, Patrick Georges, Elisabeth Reino, Daniel Vivien, François Balembois, Bernard FerrandAbstract:An output power of 450 niW at 900 nm for ~ 1 W of absorbed pump power at 790 nm is obtained from a Nd-doped strontium-lanthanum aluminate crystal (Nd: ASL) pumped by a Titanium Sapphire Laser. This wavelength is one of the shortest 4F3/2 →4I9/2 Laser transitions ever reported for a C W Nd-activated material. The slope efficiency reaches 58 %, a very high value for such a quasi-three level Laser
