Novel chirped pulses defy ‘conventional wisdom’

Novel chirped pulses defy ‘conventional wisdom’

June 16, 2021

Rochester researchers have advanced a groundbreaking technique first pioneered at the University’s Laboratory for Laser Energetics. As a result, they’ve produced chirped pulses in a way that works even with relatively low-quality, inexpensive equipment.

Rochester breakthrough in laser science earns Nobel Prize

Rochester breakthrough in laser science earns Nobel Prize

October 2, 2018

University of Rochester doctoral graduate Donna Strickland ’89 (PhD) and former optics faculty member Gérard Mourou shared the Nobel Prize in Physics today for work they undertook at the University’s Laboratory for Laser Energetics. Their breakthrough paved the way for the creating very short and very intense laser pulses now used in a variety of applications, from LASIK eye surgery to the manufacturing of materials used in cell phones.

Schumer and Gillibrand announce $80 million for LLE in Senate bill

Schumer and Gillibrand announce $80 million for LLE in Senate bill

June 5, 2018

This Senate bill must now be reconciled with the House of Representatives’ bill, which included $68 million for LLE. Both bills reject the Administration’s budget request to cut the Lab’s FY19 funding dramatically and to phase out of all federal support for LLE in three years.

A first for direct-drive fusion

A first for direct-drive fusion

September 6, 2016

Experiments have created the conditions capable of producing a fusion yield that’s five times higher than the current record laser-fusion energy yield. The new work represents an important advance in a long-standing national research initiative to develop fusion as an energy source.
