“…Therefore, as the signal wave is amplified, the DFG process can also be viewed as optical parametric amplification (OPA) [ 18] of the signal wave due to the high intensity of the pump wave (dye laser). This concept was already realized in early work on DFG [ 19 ] and has recently been nicely demonstrated for DFG in LiNbO3 [20]. Due to parametric amplification of the signal wave, its intensity will always increase to a maximum determined by overlap factors and other parameters of the experiment, independent (beyond a minimum level) of the signal input energy.…”

An efficient method for generation of high energy pulsed ir light between 0.9 and 1.5 ltm is described. The technique uses difference frequency mixing of pulsed, visible dye and Nd:YAG laser light in a 10 mm long BBO crystal. Quantum efficiencies of up to 23% and ir pulse energies up to 4.5 mJ are demonstrated. The low shot-to-shot fluctuations of difference frequency generation in BBO make this technique an attractive alternative to the conventional optical parametric oscillator or Raman shifting methods that are currently used to access this spectral region.

“…In this section of the review, we will mainly focus on DFG, OPA and OPO processes. These interactions were observed for the first time in 1963 for DFG [119] and in 1965 for OPA [120,121] and OPO [122]. Owing to the narrow-spectral 370 band of the lasers available in the early 1960s, all of these interactions led to small spectral bandwidth and little tunability.…”

Recent developments in laser sources operating in the mid-IR (3 -8 µm), have been motivated by the numerous possibilities for both fundamental and applied research. One example is the ability to unambiguously detect pollutants and carcinogens due to the much larger oscillator strengths of their absorption features in the mid-IR spectral region compared with the visible. Broadband sources are of particular interest for spectroscopic applications since they remove the need for arduous scanning or several lasers and allow simultaneous use of multiple absorption features thus increasing the confidence level of detection. In addition, sources capable of producing ultrashort and intense mid-IR radiation are gaining relevance in attoscience and strong-field physics due to wavelength scaling of re-collision based processes. In this paper we review the state-of-the-art in sources of coherent, pulsed mid-IR radiation. First we discuss semi-conductor based sources which are compact and turnkey, but typically do not yield short pulse duration. Mid-IR laser gain material based approaches will be discussed, either for direct broadband mid-IR lasers or as narrowband pump lasers for parametric amplification in nonlinear crystals. The main part will focus on mid-IR generation and amplification based on parametric frequency conversion, enabling highest mid-IR peak power pulses. Lastly we close with an overview of nonlinear post-compression techniques, for decreasing pulse duration to the sub-2-optical-cycle regime.

“…In this case, researchers for the first time observed the second-harmonic generation at an optical frequency. 4 Shortly after this discovery, several other coherent optical frequency-mixing effects (such as optical sum-frequency effect, 5 optical third-harmonic effect, 6 optical rectification effect, 7 optical differencefrequency effect, 8,9 and optical parametric amplification/oscillation as well 10,11 ) were sequentially observed. Only since that time, researchers had realized that all these new effects could be reasonably explained by replacing the linear term on the right-hand side of Eq.…”
