Thin Film Deposition of Boron Nitride by Femtosecond Laser Pulses with Different Wavelengths

Thin film deposition of hexagonal boron nitride was carried out using fundamental and second harmonic waves of a femtosecond Ti:sapphire laser. Morphological investigation of the deposited thin films showed that the number of fragments and the ablation threshold were smaller in the case of second harmonic wave ablation than fundamental wave ablation.
