The mid-infrared spectral region offers an expansive window for applications including molecular spectroscopy, environmental monitoring and biomedical imaging. Supercontinuum generation in this domain ...

Experimental setup for computational temporal ghost imaging based on frequency downconversion. Preprogrammed probing temporal patterns generated from the arbitrary waveform generator (AWG) are applied ...

Physicists in the Harvard John A. 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 ...

For example, they can concentrate the energy of long-wavelength infrared light into extremely small volumes, even down to tens of nanometers, as well as effectively move heat away from the source.
