The Fresnel diffraction patterns of the probe pulse due to noncollinear degenerate phase modulation induced by a femtosecond pump pulse were extracted from the set of inline digital holograms and analyzed. The absolute values of the nonlinear refractive index of both the sample glass substrate and the deposited layer of quantum dots were evaluated using the proposed technique. To characterize the inhomogeneous distribution of the samples\u2019 nonlinear optical properties, we proposed plotting an optical nonlinearity map calculated as a local standard deviation of the diffraction pattern intensities induced by noncollinear degenerate phase modulation.<\/jats:p>","DOI":"10.3390\/jimaging8030074","type":"journal-article","created":{"date-parts":[[2022,3,16]],"date-time":"2022-03-16T03:34:13Z","timestamp":1647401653000},"page":"74","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Investigation of Nonlinear Optical Properties of Quantum Dots Deposited onto a Sample Glass Using Time-Resolved Inline Digital Holography"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0502-7769","authenticated-orcid":false,"given":"Andrey","family":"Belashov","sequence":"first","affiliation":[{"name":"Ioffe Institute, 194021 Saint-Petersburg, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1507-3280","authenticated-orcid":false,"given":"Igor","family":"Shevkunov","sequence":"additional","affiliation":[{"name":"Faculty of Information Technology and Communication Sciences, Tampere University, 33720 Tampere, Finland"}]},{"given":"Ekaterina","family":"Kolesova","sequence":"additional","affiliation":[{"name":"Faculty of Photonics, ITMO University, 197101 Saint-Petersburg, Russia"}]},{"given":"Anna","family":"Orlova","sequence":"additional","affiliation":[{"name":"Faculty of Photonics, ITMO University, 197101 Saint-Petersburg, Russia"}]},{"given":"Sergei","family":"Putilin","sequence":"additional","affiliation":[{"name":"Faculty of Photonics, ITMO University, 197101 Saint-Petersburg, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6646-6207","authenticated-orcid":false,"given":"Andrei","family":"Veniaminov","sequence":"additional","affiliation":[{"name":"Faculty of Photonics, ITMO University, 197101 Saint-Petersburg, Russia"}]},{"given":"Chau-Jern","family":"Cheng","sequence":"additional","affiliation":[{"name":"Information Optics and Photonics Laboratory, Institute of Electro-Optical Engineering, National Taiwan Normal University, Taipei 11677, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8866-7592","authenticated-orcid":false,"given":"Nikolay","family":"Petrov","sequence":"additional","affiliation":[{"name":"Faculty of Photonics, ITMO University, 197101 Saint-Petersburg, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"875","DOI":"10.1364\/JOSAB.4.000875","article-title":"Nonlinear refractive-index measurements of glasses using three-wave frequency mixing","volume":"4","author":"Adair","year":"1987","journal-title":"J.
