“…GaAs, which does not offer birefringence nor ferroelectric properties is processed to accommodate QPM by epitaxial growth in which the optical axis of GaAs is periodically reversed. Vasilyev et al [16] recently demonstrated a fiber optically pumped DFG source utilizing an orientation patterned QPM GaAs with a wide tunability (7.6-8.2 μm) and high output power (0.5 mW). Earlier work by Bisson et al demonstrated a similar source using QPM GaAs applied to cavity ring down spectroscopy [17].…”

Tunable mid-infrared laser sources are the key to precision optical trace gas detection. Difference-frequency generation (DFG) based laser sources are among a few practical laser sources that have demonstrated ultra-high detection sensitivities during real-world applications when combined with appropriate signal enhancing and noise reduction spectroscopic techniques. This article will discuss the technical approaches, illustrate application examples of DFG sources, and offer perspectives to competing technologies.A He-Ne alignment laser visualizes a reentrant beam pattern of a 100 m, 182 pass astigmatic Herriott multi-pass absorption cell used in highly sensitive trace gas DFG spectrometers.

“…They rely on a specific epitaxial growth step based on hydride-vapor-phase epitaxy (HVPE) carried out on a prepatterned substrate [37,38]. Cw MIR DFG sources based on OP-GaAs with output powers between nW and mW were demonstrated [39][40][41], and pulsed optical parametric amplification obtained with a 53 dB gain [42].…”

We demonstrate a robust and simple method for measurement, stabilization and tuning of the frequency of cw mid-infrared (MIR) lasers, in particular of quantum cascade lasers. The proof of principle is performed with a quantum cascade laser at 5.4 µm, which is upconverted to 1.2 µm by sum-frequency generation in orientation-patterned GaAs with the output of a standard high-power cw 1.5 µm fiber laser. Both the 1.2 µm and the 1.5 µm waves are measured by a standard Er:fiber frequency comb. Frequency measurement at the 100 kHz-level, stabilization to sub-10 kHz level, controlled frequency tuning and long-term stability are demonstrated.

“…Since then, significant progress in material properties [4] (optical losses down to 0.016 cm -1 have been measured) led to several laboratory demonstrations suited to many applications [5][6][7][8]. The present paper focuses on the next step toward field experiments based on multi-watt pulsed sources.…”

Among quasi-phase matching (QPM) materials, PPLN suffers from a limited transparency, strongly limiting both the output power and the beam quality above 4 µm. We are developing a new QPM technology based on OrientationPatterned Gallium Arsenide (OP-GaAs) crystals, transparent up to 16 µm and showing excellent nonlinear and thermal properties and very low losses (<0.02 cm -1 ).We demonstrated with such samples a high-repetition rate tunable OPO attractively pumped by a remote Thulium fiber laser and integrated in a 25x30x6 cm transportable head. A 3 W level output in the 3-5 µm range was obtained with a 53% efficiency and an unprecedented beam quality (M 2 =1.4), making this module most suited to study directed infrared countermeasures (DIRCM).
