For attosecond technology, carrier envelope phase (CEP) stabilization in the few-cycle regime combined with high repetition rates is essential for studying ultrafast electronic processes in atoms, molecules, solids, and complex many body systems. Therefore, a laser system was designed, where the laser pulses are generated from a single white-light-generation (WLG) source operating at 1 MHz, provding dual simultaneous CEP stable pulses at 2 µm and 800 nm with pulse duations of <40 fs and <10 fs, and pulse energies of 1 µJ and 1.2 µJ, respectively. The system is robust and compact, with a footprint of less than a square meter.
