High-Performance Ultrafast Lasers That Fit on a Fingertip

by

New high-performance ultrafast lasers are being made on nanophotonic chips. The new work centers on miniaturizing mode-lock lasers — a unique laser that emits a train of ultrashort, coherent light pulses in femtosecond intervals, which is an astonishing quadrillionth of a second. Ultrafast mode-locked lasers are indispensable to unlocking the secrets of the fastest timescales …

DARPA Wants to Create Portable Atomic Clocks

by

Global Positioning Systems (GPS) are vital for the military for precision warfare but GPS can be jammed by military opponents. DARPA has announced the Robust Optical Clock Network (ROCkN) program, which aims to create optical atomic clocks with low size, weight, and power (SWaP) that yield timing accuracy and holdover better than GPS atomic clocks …
