1 MHz, few-cycle, CEP stable OPCPA with dual channel output at 800 nm and 2 µm wavelength

A high repetition rate, optical parametric chirped-pulse amplifier (OPCPA) with dual output at 800 nm and 2 µm is presented. White light seeded, CEP stabilized pulses with 9.1 fs are achieved on less than a square-meter footprint.
