Optical frequency combs in space bear the prospect of dramatically improving satellite navigation and they may pave the pathway for various space applications like satellite formation flights, global satellite navigation, earth observation, and satellite-based fundamental tests of physical constants [1]. Here we report on a precision ranging system based on a dual-comb architecture aiming for fast...
We generate 260 μJ energy optical pulses at 7 μm with an OPCPA pumped by an optically synchronized 2 μm picosecond CPA system. The mid-IR pulses exhibit a bandwidth supporting sub-4 optical cycle duration.
The relative and absolute phases of femtosecond 1.03-μm pump, 1.55-μm signal and 3.09-μm idler pulses are stabilized paving the way for the generation of optimized driver-waveforms for higher-order-harmonic generation and electron impulsive momentum transfer.
The development of high finesse resonators for broadband frequency combs enabled the extension of the versatile frequency comb technique into the extreme ultraviolet with all its implications. We describe new developments in this field.
Er3+-doped fiber-lasers efficiently generate frequency-combs for optical frequency metrology. 3.5 nJ energy, 35 fs duration and 100 MHz repetition-rate laser pulses are used to obtain an octave spanning frequency-comb in the visible.
