This study challenges their supremacy by investigating a cost\u2010effective alternative: a frugal all\u2010fiber picosecond laser source. We first conduct a pump\u2010probe experiment to characterize cavitation bubbles in water based on the laser pulse's temporal profile. Picosecond pulses concentrate energy in a confined volume near the focal point, allowing for more precise material interaction than femtosecond pulses. A distortion in the temporal profile, often seen as a flaw, paradoxically further reduces cavitation bubble size. These findings are then applied to ex\u00a0vivo porcine cornea cutting tests. Results show that 1.5\u2009ps pulses with a distorted profile create sharp, consistent cuts. This study reveals that a cost\u2010effective picosecond laser can rival femtosecond lasers in precision, paving the way for more accessible corneal laser\u2010assisted surgery.<\/jats:p>","DOI":"10.1002\/jbio.70356","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T01:30:45Z","timestamp":1790645445000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Study
