Injection-seeded optical parametric oscillator for effective change frequency era in mid-IR

Progress improvement of AgGaSe2 one crystal using the vertical Bridgman method with continual ampoule rotation and its characterization

Matters is often refined further while in the search engine results. The Topic aspect will expose the higher-degree topics linked to the articles returned in the search engine results. SPECIAL COLLECTIONS

Using a LiTaO(3) retarder is instructed to obtain an orthogonal state of polarization involving OPO outputs that happen to be essential for successful pumping of the AgGaSe(two) crystal.

AgGaSe/sub two/ crystal development has actually been understood by an enhanced Bridgman procedure with just a 1-zone vertical progress furnace. The website technique is to produce the reliable-liquid interface go from The underside…

Generally, not all responses to the above questions are "Sure", so You need to stike a equilibrium amongst these components to discover the very best Alternative on your methods. For example, to obtain a SHG crystal for Ti:Sapphire laser at 800nm, with the heart beat width of 40fs, along with the expected pulse broadening result less than 20fs. KTP, AgGaSe2 or AgGaS2 can't reach phase matching of SHG800nm; LiIO3's problems threshold is not really higher adequate; Equally BBO and KDP are suitable, nevertheless, BBO's conversion effieicy is increased than KDP, and 100micron BBO SHG800nm can only make pulse broadening outcome of 19fs.

electronic transitions and also the band gaps Eg step by step boost as being the lithium written content will increase, in keeping with

A completely new nonlinear optical crystal Li0.81Ag0.19InSe2 with balanced Qualities for productive nonlinear conversion inside the mid-IR region

The substitute of half with the significant Ag�?cations with light-weight Li�?increases the band gap to two.2 eV (vs. one.seven eV in AgGaSe2). The LDT benefit in AgLiGa2Se4 increases 5 situations as compared to that in AgGaSe2, while keeping a comparatively huge NLO susceptibility of 26 pm V⁻�? Furthermore, the thermal expansion coefficients in AgLiGa2Se4 are roughly two instances decreased in complete worth in comparison with AgGaSe2, which is beneficial to the massive crystal expansion. Every one of these strengths would make AgLiGa2Se4 a completely new promising NLO crystal for mid‐IR laser applications.
