“…Since the investigated crystals belong to the space group Pna2 1 there are only five independent components of the SHG tensor, namely, the (2) 333 (ω), (2) 311 (ω), (2) 322 (ω), (2) 232 (ω) and (2) 113 (ω). The complex second-order nonlinear optical susceptibility tensor (2) ijk (−2ω; ω; ω) can be generally written as (2) ijk (ω).…”

“…Among the A I B III C VI 2 ternary chalcogenides, one subfamily LiB III C VI 2 where the noble metal (Ag) is substituted by Li, B by Ga and C by S or Se, the replacement of the metallic cations (Ag + , Cu + ) by lighter Li + cation changes for C S or Se the crystal structure form the chalcopyrite one tetragonal structure to orthorhombic structure [2]. The orthorhombic crystals are biaxial and iso-structural to KTiOPO 4 (KTP), offering an extended phase-matching capability in the three different crystallographic planes [2]. The growth of LGS crystal was in as early as 1947 [3], when its average refractive index, density and melting point were estimated.…”

“…Some of them have even been used for nonlinear mixing schemes [17], but most of them are still under development. For our wavelength mixing scheme suitable are the nonlinear materials AgGaS 2 (AGS), GaSe (GS), LiInSe 2 (LISe), and LiGaSe 2 (LGSe) [18]. AGS and GS are well established, but show high TPA.…”

We present simulations for a design of a highenergy single-stage mid-IR difference frequency generation adapted to a two-color Ti:sapphire amplifier system. The optimized mixing process is based on chirped pulse difference frequency generation (CP-DFG), allowing for a higher conversion efficiency and reduced two-photon absorption losses. The numerical start-to-end simulations include stretching, chirped pulse difference frequency generation and pulse compression. Realistic design parameters for commercially available nonlinear crystals (GaSe, AgGaS 2 , LiInSe 2 , LiGaSe 2 ) are considered. Compared with conventional unchirped DFG directly pumped by Ti:sapphire technology, we predict a threefold increase in the quantum efficiency. Our CP-DFG scheme provides up to 340 lJ pulse energy directly at 7.2 lm when pumped with 8 mJ and supports a bandwidth of up to 350 nm. The resulting 240 fs mid-IR pulses are inherently phase stable.

“…In the past few years, some ternary chalcogenides containing lithium element, such as LiGaS 2 (LGS) and LiInS 2 (LIS) [28,29], have been discovered. The replacement of silver cation with main-group cationic elements, such as Li + ion, increases their band gap and leads to a much higher LDT.…”

Research progress on mid-IR nonlinear optical crystals with high laser damage threshold in China

Nonlinear optical (NLO) crystals have been playing an increasingly important role in laser science and technology. The NLO crystals used in the middle infrared (mid-IR) region, compared with the NLO crystals in the other wavelength regions, are still not good enough for the application of high-energy laser. The main defect is that their laser damage thresholds (LDT) are low. Chinese scientists have made a lot of important contributions to the UV and visible NLO crystals. In the last decade, they also did a lot of work on the mid-IR NLO materials. The main purpose of these researches is to increase the LDT and simultaneously balance the other properties. This paper presents a brief summary of their research progress in this topic on three types of materials: chalcogenides, oxides, and halides. The emphasis is put on the design strategy and quality control of the crystals.
