A route to high peak power and energy scaling in the mid-IR chirped-pulse oscillator-amplifier laser systems
The paper introduces a new route towards the ultrafast high laser peak power
and energy scaling in a hybrid mid-IR chirped pulse oscillator-amplifier
(CPO-CPA) system, without sacrificing neither the pulse duration nor energy.
The method is based on using a CPO as a seed source allowing the beneficial
implementation of a dissipative soliton (DS) energy scaling approach, coupled
with a universal CPA technique. The key is avoiding a destructive nonlinearity
in the final stages of an amplifier and compressor elements by using a chirped
high-fidelity pulse from CPO. Our main intention is to realize this approach in
a Cr2+:ZnS-based CPO as a source of energy-scalable DSs with well-controllable
phase characteristics for a single-pass Cr2+:ZnS amplifier. A qualitative
comparison of experimental and theoretical results provides a road map for the
development and energy scaling of the hybrid CPO-CPA laser systems, without
compromising pulse duration. The suggested technique opens up a route towards
extremely intense ultra-short pulses and frequency combs from the multi-pass
CPO-CPA laser systems that are particularly interesting for real-life
applications in the mid-IR spectral range from 1 to 20 um.Comment: 16 pages, 14 figure
