Combining Lasers Leads to More Flexible Pulse Control

Facebook X LinkedIn Email
SOUTHAMPTON, England, Jan. 22, 2015 — Every laser has its limitations in terms of repetition rate and pulse characteristics, but bringing five lasers together in one system could make those limitations vanish. A device developed at the University of Southampton does just that to generate wide-bandwidth optical signals with arbitrary amplitude and phase profiles — flexibility that could be useful for telecommunications, metrology, sensing and materials processing. The new method relies on the coherent combination of multiple semiconductor lasers, each operating in CW mode at different frequencies. Through the...Read full article
