We developed an optimized, carrier-envelope-phase-stable Ti:sapphire oscillator that generates 6 nJ pulses compressible to under sub- two- optical-cycles in duration. We used the optimized oscillator to demonstrate carrier-envelope-phase-sensitive (CEP-sensitive) photoemission from metallic nanoparticles in the near-infrared.
