Self-similar optical wave collapse: Observation of the Townes profile

Research output: Contribution to journalArticlepeer-review


An overview is given of detailed experimental observations of the universal, self-similar nature of optical wave collapse due to Kerr nonlinearity self-focusing for randomly distorted and elliptical beams. The observations reveal that the spatial profile evolves to a specific circularly symmetric shape, known as the Townes profile, for elliptically shaped or randomly distorted input beams.
