Mono cycle photonics and optical scanning tunneling microscopy : route to femtosecond Ångstrom technology Femtosecond Nanometer Technologydeals with both the ultrashort laser pulse technology in the few to mono cycle region and the laser surface controlled scanning tunneling microscopy (STM) extending into the spatiotemporal extreme technology. The former covers the theory of nonlinear pulse propagation beyond the slowly varying envelope approximation the generation and active chirp compensation of ultrabroadband optical pulses the amplitude and phase characterization of few to mono cycle pulses and the feedback field control for the mono cycle like pulse generation. In addition the wavelength multiplex shaping of ultrabroadband pulses and the carrier phase measurement and control of few cycle pulses are described. The latter covers the CW laser excitation STM the femtosecond time resolved STM and atomic level surface phenomena controlled by femtosecond pulses.
