Physicists at Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that ...

First on-chip, picosecond MIR laser pulse generator to requires no external components.

Physicists at Harvard have developed a powerful new laser-on-a-chip that emits bright pulses in the mid-infrared spectrum – ...

Published in Nature, the research is the first demonstration of an on-chip, picosecond, mid-infrared laser pulse generator that requires no external components to operate. The device can make what ...

The pulse generator itself is the single 2N3904 on the right. When you are a Hackaday writer with some oscilloscope bandwidths to measure, you need a picosecond avalanche pulse generator ...

The company is leading in the global market for scientific picosecond lasers ... A broad range of available laser parameters, such as pulse duration, wavelength, average power, pulse energy, ...

This effect allows the team to track the magnetic field evolution by analyzing the polarization rotation of a femtosecond laser pulse. "With this approach, we achieved sub-picosecond resolution ...

Clinics and salons that offer hair and skin treatments. Rejuvenate with therapies that deliver lasting results for total wellness.

Of course, if you need to get down to picosecond timescales, an avalanche pulse generator might be more your speed. Video after the break.
