This sensing capacity is enabled by quantifying their narrow-linewidth emission spectra, which is presently challenging to do at high speeds. In this work, we demonstrate rapid snapshot hyperspectral imaging of intracellular lasers. Using integral field mapping with a microlens array and a diffraction grating, we obtain images of the spatial and spectral intensity distribution from a single camera acquisition. We demonstrate widefield hyperspectral imaging over a 3\u2009\u00d7\u20093 mm\n                    <jats:sup>2<\/jats:sup>\n                    field of view and volumetric imaging over 250\u2009\u00d7\u2009250\u2009\u00d7\u2009800 \u00b5m\n                    <jats:sup>3<\/jats:sup>\n                    (XYZ) volumes with a lateral (XY) resolution of 5 \u00b5m, axial (Z) resolution of 10 \u00b5m, and a spectral resolution of less than 0.8\u2005nm. We evaluate the performance and outline the challenges and strengths of snapshot methods in the context of characterizing the emission from intracellular lasers. This method offers new opportunities for a diverse range of applications, including high-throughput and long-term biosensing with intracellular lasers.\n                  <\/jats:p>","DOI":"10.1364\/oe.498022","type":"journal-article","created":{"date-parts":[[2023,8,23]],"date-time":"2023-08-23T12:00:38Z","timestamp":1692792038000},"page":"33175","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Snapshot hyperspectral imaging of intracellular lasers"],"prefix":"10.1364","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4605-957X","authenticated-orcid":true,"given":"Soraya","family":"Caixeiro","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02wn5qz54","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8378-7261","authenticated-orcid":true,"given":"Philip","family":"Wijesinghe","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02wn5qz54","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6534-9009","authenticated-orcid":true,"given":"Kishan","family":"Dholakia","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02wn5qz54","id-type":"ROR","asserted-by":"publisher"}]},{"name":"The University of Adelaide"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Malte C.","family":"Gather","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02wn5qz54","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2023,9,20]]},"reference":[{"key":"oe-31-20-33175-R1","doi-asserted-by":"publisher","first-page":"452","DOI":"10.1038\/s41566-020-0631-z","volume":"14","author":"Schubert","year":"2020","journal-title":"Nat.
