Crystal development, composition, and optical Houses of new quaternary chalcogenide nonlinear optical crystal AgGaGeS4
Injection-seeded optical parametric oscillator for economical big difference frequency era in mid-IR
eight and 1.1 occasions that of AGS. These Houses originate through the GaS4, GeS4, and SnS4 tetrahedral blocks while in the constructions of the sulfides. Equally compounds also show a wide transparency range and sort-I section-matching habits, which assist their higher potential in high-electrical power laser applications. This operate sheds new light-weight on the event of promising mid-IR NLO supplies by combining different NLO-active motifs.

The basic optical absorption edges in these LixAg1−xInSe2 compounds are established in the immediate
AgGaSe/sub two/ crystal growth has been recognized by an enhanced Bridgman procedure with only a 1-zone vertical growth furnace. The procedure is to produce the strong-liquid interface move from the bottom…
A tunable mid-infrared optical parametric oscillator has been demonstrated using a noncritically period matched AgGaSe/sub two/ crystal with pump wavelength tuning. Regular ability experiments have…

The substitute of 50 % of your large Ag�?cations with light-weight Li�?improves the band gap to 2.2 eV (vs. 1.7 eV in AgGaSe2). The LDT value in AgLiGa2Se4 boosts 5 periods as compared to that in AgGaSe2, while maintaining a relatively large NLO susceptibility of 26 pm V⁻�? In addition, the thermal growth coefficients in AgLiGa2Se4 are around two instances lessen in complete price when compared with AgGaSe2, which is beneficial to the massive crystal development. These pros would make AgLiGa2Se4 a whole new promising NLO crystal for mid‐IR laser purposes.
