“…As a representative member of materials belonging to NLO family, KTA possesses high chemical and thermal stability [2]. Additionally, other properties such as high nonlinear optical coefficients, appropriate birefringence, phase matching, efficiency and a wide range of transparency make potassium titanyl arsenate a very interesting material for different applications in nonlinear optical and electrooptical devices [2][3][4][5][6]. Furthermore, unique NLO properties together with high optical damage threshold revealed KTA as an excellent material for applications in the infrared (IR) spectral range: second harmonic generation (SHG), optical frequency conversion and manufacturing optical waveguides.…”

“…Furthermore, unique NLO properties together with high optical damage threshold revealed KTA as an excellent material for applications in the infrared (IR) spectral range: second harmonic generation (SHG), optical frequency conversion and manufacturing optical waveguides. It is noteworthy to mention also that, KTA reveals higher electrooptic and nonlinear values 30% and 60% (for SHG under pumping at = 1.32 m), respectively, and lower absorption in the spectral region ranging from 3 to 5 m as compared with those of potassium titanyl phosphate, KTiOPO 4 (KTP) [3,[7][8][9]. Two-dimensional KTP-family crystals grown in ordered macroporous silicon templates reveal unique photonic properties [10].…”

“…The mechanism has at present not been identif ied to our knowledge, but it is possible that a combination of both effects exists, and the effect is very similar to one that we demonstrated at 3.5 mm. 1 In that study we used an InGaAs photodiode to perform autocorrelation measurements without using a frequency-doubling crystal. A similar effect was exploited to autocorrelate pulses at 1.5 mm by use of a silicon photodiode.…”

We present results showing that, when it is used as a photodetector, a light-emitting diode (LED) has a power-dependent response that can be used for sensitive detection and characterization of picosecond and femtosecond laser pulses. A characterization of a typical LED is presented at 800 nm, and we demonstrate how this effect can be used to construct an extremely compact novel autocorrelator based on a Wollaston prism.

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.
