  • Abstract
    Ablations of Cr film on fused silica with ultrashort double pulses were investigated. Periodic microripple structures were formed on the Cr film after irradiating by trains of double laser pulses. Experimental results should be helpful for us to understand the electron phonon relaxation time for femtosecond laser micromachining.
