Mechanically tunable optofluidic distributed feedback dye laser

Demetri Psaltis

A continuously tunable optofluidic distributed feedback (DFB) dye laser was demonstrated on a monolithic replica molded poly(dimethylsiloxane) (PDMS) chip. The optical feedback was provided by a phase-shifted higher order Bragg grating embedded in the liqu ...

Single mode optofluidic distributed feedback dye laser

Demetri Psaltis

Single frequency lasing from organic dye solutions on a monolithic poly(dimethylsiloxane) (PDMS) elastomer chip is demonstrated. The laser cavity consists of a single mode liquid core/PDMS cladding channel waveguide and a phase shifted 15th order distribut ...

Photonic crystal nanocavity array laser

Hatice Altug

We demonstrate a new type of laser composed of an array of coupled photonic crystal nanocavities that enables high differential quantum efficiency and output power, together with a low threshold power comparable to those of single photonic crystal cavity l ...

Ozone detection by differential absorption spectroscopy at ambient pressure with a 9.6 mu m pulsed quantum-cascade laser

Hubert van den Bergh, Bertrand Calpini, Valentin Simeonov, Jérôme Faist

We report direct absorption spectroscopic detection of ozone at ambient pressure with a pulsed, DFB quantum-cascade laser (QCL) tuned within 1044-1050 cm(-1) by temperature scanning. Wavelength calibration curves were derived from FTIR and CO2 spectra and ...

Photosensitivity and bragg grating technology for upconversion all-fiber lasers

Marcel Zeller

Fiber lasers are compact lightsources with high intrinsic beam quality and high efficiency. The lasing spectrum ranges from the blue to the near infrared and is achievable using fibers with different dopants and glass compositions. All-fiber lasers are cha ...

Epitaxial growth and optical characterization of BaSO4:Mn6+ layers for novel coherent light sources

Because of the strong electron-phonon coupling of the emitting 3d orbital in transition-metal (TM) ions, 3d systems exhibit luminescence with typically several hundred nm of spectral bandwidth. TM-ion-doped materials are, therefore, of high interest for ap ...

Cristal composite SLAB pompé latéralement par diodes laser

This work presents the development of an original concept of a side pumped diode pumped crystal laser for the generation of a high power near diffraction limited beam for material processing applications such as cutting, marking and drilling. An approach b ...

Ethylene spectroscopy using a quasi-room-temperature quantum cascade laser

Luc Thévenaz, Philippe Robert

Spectroscopic measurements on ethylene were performed using a quasi-room-temperature quantum cascade (QC) laser operated in pulsed mode in the 10.3 μm range. Using transmission spectroscopy, a broadening of the ethylene absorption spectrum was observed wit ...

Mesure de traces de gaz à l'aide de lasers à semi-conducteur

Infrared spectroscopy using semiconductor lasers is a promising technique for trace gas detection. It allows a continuous and real time monitoring of several species, with a high sensitivity and a good selectivity. Among all the possible methods two are pa ...

Highly efficient optically pumped NH3 laser with near diffraction limited output

Thomas Rizzo, Joachim Makowe

We present the design of a highly efficient, pulsed ammonia laser which is optically pumped by a commercial TEA CO2 laser and is line tunable in the spectral range of 780-930 cm(-1). The power, spectral, and temporal characteristics of the laser have been ...
