An optical parametric chirped-pulse amplifier (OPCPA) system is presented, capable of providing ultrashort laser pulses at all relevant central wavelengths, from 920 to 1700 nm, for 2- and 3-photon imaging applications with repetition rates up to 10 MHz for ultrafast image acquisition.
Active carrier envelope phase (CEP) stabilization in the few-cycle regime is essential for most attosecond experiments, e.g. studying the coherent evolution of electronic structure and dynamics in solids or complex many body phenomena crystals. Here, we present a dual-channel optical parametric chirped-pulse amplifier (OPCPA) design providing CEP stable, sub 9 fs pulses around 800 nm center wavelength as a high-harmonic driver for attosecond experiments. Additionally, a second 1.7 - 2 μm CEP stable outlet is available. Two OPCPA designs (a) high repetition rate and (b) a high pulse-energy system will be demonstrated.
