We are studying the laser ablation of ceramics and semiconductors by the femtosecond laser (800 nm wavelength, 100 fs pulse duration) in air. The ceramics (Al2O3) and the silicon single crystal (<100>, P-types) were used as the target material. The crater profiles were analyzed using the confocal laser scanning microscope. We used two methods to evaluate the ablation rate. The ablation thresholds...
Surface modification of crystalline Si by a femtosecond laser at room temperature in air was studied. The femtosecond laser pulses (800 nm wavelength, 100 fs pulse duration, 1 kHz repetition rate) were focused on the crystalline Si targets (p type, 99.999% purity, (100) direction) by a plano-concave lens with a focal length of 100 mm. It was found that there are four threshold fluences which characterize...
