Home / Optical module generates light pulses
Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic . Lasers and related devices have been found to have an amazing potential for generating light pulses with very special properties: There is a wide range of techniques for generating pulses with durations of nanoseconds, picoseconds, or even femtoseconds with. Modern communication networks rely on optical transceivers to transfer data at the speed of light. It interfaces between fiber optical networks and electronic computing devices such s into light pulses and vice-versa.
We demonstrate an implementation of this approach by efficiently deflecting ultrashort laser pulses using ultrasound waves in ambient air, without the use of transmissive solid media.
