Researchers develop a laser that produces the strongest ultra-short laser pulses to date

Researchers at ETH Zurich have set a new record for the strongest laser pulses ever created by a laser oscillator.

At 550 watts of average power they surpass the previous maximum by more than 50 percent .

At the same time, they are extremely short—they last less than a picosecond, or a millionth of a millionths of a second , and exit the laser in a regular sequence at a high rate of five million pulses per second .

"All in all, one can say that with our pulse lasers we have shown that laser oscillators are a good alternative to amplifier-based laser systems and that they enable new and better measurement," Keller says.
