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 ultra-broadband 6.5 µm pulses with 2.3 cycle transform limit and 85 pJ energy at 100 MHz from a phase-coherent, two-color, two-arm Er:Tm:Ho all-fiber MOPA system in CdSiP2.
We present an all fiber THz spectrometer based on a novel scanning technique without any external moveable delay stage. The optical delay between the pump and probe pulses and thus the scanning range is controlled via the repetition rate of the laser source.
We use low finesse Fabry-Perot cavities in series to generate frequency combs with large mode spacing by simultaneously maintaining high spectral bandwidth. The attenuation of laser modes closest to the pass band exceeds 70 dB relative to the modes centered within the pass band for a 5 GHz Fabry-Perot filtering a 250 MHz frequency comb.
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.
