Of particular interest to x-ray free-electron laser light source facilities is the enhanced self-amplified spontaneous emission (ESASE) technique. ESASE requires an ultrafast (20-50 fs), high peak power, high repetition rate, reliable laser system working in the midinfrared spectral range (>= 2 mu m). These requirements can be met by a novel ultrafast midinfrared laser system based on optical parametric chirped-pulse amplification (OPCPA). OPCPA is a technique ideally suited for production of ultrashort laser pulses at the center wavelength of 2 mu m. Some of the key features of OPCPA are the wavelength agility, broad spectral bandwidth, and negligible thermal load. The ESASE-compatible laser technology analysis and the preliminary OPCPA simulation results are presented.
