Peak-power wall.
Long upper-state lifetimes of thulium-hosted crystals offer bypass of prohibitive diode infrastructure costs that bottleneck low-repetition-rate, multi-joule laser architectures...

Schematic comparison of carrier injection through a) 1 + 2 and b) 2 + 3 quantum interference within a semiconductor. The higher-order 2 + 3 process concentrates carriers into a narrower range of momentum-space directions and produces a more directional photocurrent.

To build a quantum sensor, light must be prepared in a carefully controlled state where its frequency, polarization, and intensity are well controlled. The polarization of blue light is altered before it’s used to cool the atoms to near absolute zero.

FIGURE 1. Top: An OFC generated by a modelocked laser. Bottom: A periodic pulse train in the time domain corresponds to a series of discrete frequencies in the frequency domain. The frequency comb is shifted in frequency space by a carrier-envelope offset frequency fceo, which arises from the carrier envelope phase slip Δφ between successive pulses. Apart from this offset, the comb consists of equally spaced spectral lines separated by the repetition rate frep.
