“…5 Alkali halide (AH) crystals containing colour centres (CCs) have been extensively studied for the realization of optically pumped tuneable solid-state lasers. 6 Little attention, however, has so far been devoted to AH films and to their application in the development of innovative miniaturized coherent light sources, like active waveguides and microcavities. Broad band single-mode active channel waveguides have been realized for the first time at the surface of LiF single-crystals 7 and films 8 thermally evaporated on LiF bulk.…”

Lithium fluoride (LiF) films treated by lowenergy electrons represent a very promising candidate for the realization of miniaturized broad band optical devices like active waveguides and microcavities. The main properties, in particular the refractive index, density, structure and microstructure, of polycrystalline LiF films grown by thermal evaporation on amorphous and crystalline substrates are discussed, together with their influence on colour centres formation induced by low-energy electron beam bombardment and on the choice of the main irradiation conditions.

“…There are several conventional tunable cw-laser systems available for the MI:R, like lead salt-diodes, color center lasers, optical parametric oscillators, and CO or CO2 side band lasers [2][3][4]. However, either they need cryogenic cooling, or do not cover all spectral regions that are of interest for the spectroscopy and in most cases these are technically complicated and relatively complex laser sources.…”

Diode laser MIR-DFG spectrometer for trace gas detection

Two cw-single mode diode-lasers (Hitachi HL 785 1 G and Toshiba TOLD 91 50) with powers of 30 and 50 mW at the center wavelengths 682 and 791 nm are applied as signal and pump sources for difference frequency generation (DFG) in an AgGaS2 crystal with a length of3O mm. For 90°t ype I phase matching tunable mid-infrared (MIR) laser radiation is obtained in the spectral range between 4.9 and 5.1 jim, while the DFG-output power is 0.2 iW. The performance of this diode-laser MTR-DFG spectrometer is shown as the absorption of CO for the P(28) rotational line around 2023 cm1 is probed in a cell and on-line in the exhaust ofan engine.

“…34,35 Other methods that can be used to generate ultrashort pulses in the mid-infrared spectral region include the free electron laser, 2,3 color-center lasers, 36 and differencefrequency mixing. 4,11,37 The OPO -OPA system offers distinct advantages over these methods for generating high-repetition-rate, high-peak power femtosecond pulses in this wavelength region.…”

“…Additionally, color-center lasers do not have sufficient pulse energy to permit performance of nonlinear experiments, and they tend to suffer from such problems as photobleaching, which makes them an unreliable source. 36 Finally, difference-frequency mixing is capable of generating short pulses with sufficient energy in the mid-infrared region. 4,37 But the high laser energies that are necessary to obtain a useful amount of infrared light require low-repetition-rate amplifiers (#1 kHz) for the mixing pulses.…”

High-repetition-rate femtosecond optical parametric oscillator–amplifier system near 3 μm

1995

View full text Add to dashboard Cite

An ultrafast laser system for the chemically important 3-mm spectral region has been constructed by means of noncritically phased-matched KTiOPO 4 optical parametric gain elements. An optical parametric oscillator, synchronously pumped by a mode-locked Ti:sapphire oscillator, generates high-quality seed pulses for an optical parametric amplifier. The optical parametric amplifier, pumped by a high-repetition-rate Ti:sapphire regenerative amplifier, amplifies the seed pulses by a factor of 520. Pulses with an energy of 550 nJ and a pulse width of 160 fs are produced at a 250-kHz repetition rate in the 3-mm region.
