Nonlinear microscopes, including multiphoton excitation fluorescence microscopy and multiple harmonic generation microscopy, have recently gained popularity for cellular and tissue imaging. Optimization of these imaging methods for minimally invasive use will require optical fibers to conduct light in a narrow space where clearance of free space is difficult. Delivery of high peak laser pulses with optical fibers is limited by the resulting dispersion of nonlinear refractive index responses. A theoretical explanation for the measured performance of these is also provided.
As for soliton communication, such a pulse train was very advantageous since the fiber laser could directly generate a limited transformation sech pulse using a soliton effect in the fiber cavity. It is also useful as an input pulse for an optical pulse compressor using the compression effect of adiabatic solitons. These compressed pulses were used for a OTDM tera bit / s transmission experiment, performing for the first time an OTDM transmission of 1.28 Tbit / s over 70 km. Since mode locked fiber lasers can easily generate a short pulse train limited by transformation, they are applicable to a variety of advanced optical communication technologies.
