  Consolidating multiple high-energy femtosecond scale lasers is expected to
enable implementation of cutting edge research areas varying from wakefield
particle accelerators to ultra-high intensity laser pulses for basic fresearch.
The ability to guide while augmenting a short-pulse laser is crucial in future
laser based TeV particle accelerators where the laser energy depletion is the
major setback. We propose, analyze and experimentally demonstrate consolidating
multiple femtosecond pulse lasers in coupled curved capillaries. We demonstrate
a proof of principle scheme of coupled curved capillaries where two femtosecond
laser pulses are combined. We found that the details of the coupling region and
injection scheme are crucial to the pulse consolidations. Furthermore, our
simulations show that high-intensity short pulse laser can be guided in a small
curvature radius capillary. Incorporating these finding in a curved capillary
laser coupler will be a significant step towards realization of meters long TeV
laser based particle accelerators.
