Effect of Repetition Rate on Femtosecond Laser-Induced Homogenous Microstructures
We report on the effect of repetition rate on the formation and surface texture of the laser induced homogenous microstructures. Different microstructures were micromachined on copper (Cu) and titanium (Ti) using femtosecond pulses at 1 and 10 kHz. We studied the effect of the repetition rate on structure formation by comparing the threshold accumulated pulse ( F Σ p u l s e ) values and the ef...
متن کاملMicromachining with a High Repetition Rate Femtosecond Fiber Laser
Industrial micromachining applications with ultrashort pulse lasers are often difficult to make practical due to the lack of robustness of the laser and the slow processing speed resulting from the low repetition rate. In the past, amplified, femtosecond lasers produced high pulse energies, but at a slow pulse repetition rate of around a kHz. The high repetition rate oscillators did not have en...

We report a three-element Kerr-lens modelocked femtosecond Cr:YAG laser which generated transform-limited 82fs pulses at 1525 nm and a pulse repetition frequency up to 4.02GHz. ©2003 Optical Society of America OCIS codes: (140.4050), (140.7090) Introduction: Progress in the refinement of Cr:YAG lasers has been ongoing since their initial conception in 1991 [1]. One of the main motivations for t...

We report a low-cost, 1 GHz repetition-rate, diode-pumped, saturable Bragg reflectors modelocked Cr:LiSAF laser, which generates nearly transform-limited 103-fs long pulses around 866 nm, with a record high peak power of 1.45 kW. 2010 Optical Society of America OCIS codes: (140.3460) Lasers; (140.3480) Lasers, diode pumped; (140.4050) Mode-locked lasers High repetition-rate femtosecond (fs) la...
متن کاملMicro-Raman spectroscopy of refractive index microstructures in silicone-based hydrogel polymers created by high-repetition-rate femtosecond laser micromachining
Micro-Raman spectroscopy was used to study silicone-based hydrogel polymers after being modified by 800 nm, 27 fs laser pulses from a Ti:sapphire oscillator at 93 MHz repetition rate. When the irradiation conditions were below the optical breakdown threshold of the polymers, no significant changes in the Raman spectra and background fluorescence were observed even when refractive index changes ...
