چکیده
High-repetition rate laser-induced damage of Ta 2 O 5 :SiO coatings was investigated at 355 nm wavelength and a repetition 30 kHz. Laser-induced thresholds with different mixture ratios were measured. The relationships between threshold the material band gap defect absorption analyzed. decreased increase in number laser pulses owing to enhancement absorption. Enhancement is attributed density mid-state defects induced by picosecond pulses. relationship ratio also

1 J, 0.5 kHz repetition rate picosecond laser.
We report the demonstration of a diode-pumped chirped pulse amplification Yb:YAG laser that produces λ=1.03 μm pulses of up to 1.5 J energy compressible to sub-5 ps duration at a repetition rate of 500 Hz (750 W average power). Amplification to high energy takes place in cryogenically cooled Yb:YAG active mirrors designed for kilowatt average power laser operation. This compact laser system wi...
متن کاملYb-fiber-laser-pumped, high-repetition-rate picosecond optical parametric oscillator tunable in the ultraviolet.
We report a compact tunable 240-MHz picosecond source for the ultraviolet based on intra-cavity frequency doubling of a signal-resonant MgO:sPPLT optical parametric oscillator (OPO), synchronously pumped at 532 nm in the green by the second harmonic of a mode-locked Yb-fiber laser at 80-MHz repetition rate. By deploying a 30-mm-long multi-grating MgO:sPPLT crystal for the OPO and a 5-mm-long Bi...
متن کاملFlexible high-repetition-rate ultrafast fiber laser
High-repetition-rate pulses have widespread applications in the fields of fiber communications, frequency comb, and optical sensing. Here, we have demonstrated high-repetition-rate ultrashort pulses in an all-fiber laser by exploiting an intracavity Mach-Zehnder interferometer (MZI) as a comb filter. The repetition rate of the laser can be tuned flexibly from about 7 to 1100 GHz by controlling ...

15 صفحه اولEffect 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...
