文摘
- •
Temporally asymmetric shaped femtosecond laser pulses lead to excitation over smaller area and larger depth in water.
- •
Transient optical properties are measured radially resolved by spectral interference in an imaging geometry.
- •
Radially resolved spectral interference shows indications of nonlinear propagation effects at high fluences.
