متن کاملAbsorption Measurements of Periodically Poled Potassium Titanyl Phosphate (PPKTP) at 775 nm and 1550 nm
The efficient generation of second-harmonic light and squeezed light requires non-linear crystals that have low absorption at the fundamental and harmonic wavelengths. In this work the photo-thermal self-phase modulation technique is exploited to measure the absorption coefficient of periodically poled potassium titanyl phosphate (PPKTP) at 1,550 nm and 775 nm. The measurement results are (84±4...
متن کاملComparison of 585 nm with 595 nm pulsed dye laser in the treatment of warts
Background and aim : The clinical management of verrucae vulgaris is often challenging and no treatment is always effective. Early studies have suggested that pulsed-dye laser (PDL) may be highly effective in the treatment of verrucae through obliteration of dilated vessels in papillary dermis. The objective of this study was to compare safety and efficacy of 585 nm with 595 nm PDL in the...
متن کاملBroadly tunable femtosecond Tm:Lu2O3 ceramic laser operating around 2070 nm.
Femtosecond mode locking of a Tm-doped Lu2O3 ceramic laser is reported. Transform-limited pulses as short as 180 fs are generated at 2076 nm with an average output power of 400 mW and a pulse repetition frequency of 121.2 MHz. An output power up to 750 mW can be reached at the somewhat longer pulse duration of 382 fs. Femtosecond pulse generation is realized in the 2030-2100 nm spectral range. ...
متن کاملFemtosecond laser micro-structuring of aluminium under helium
The interaction of 180 fs, 775 nm laser pulses with aluminium under a flowing stream of helium at ambient pressure have been used to study the material re-deposition, ablation rate and residual surface roughness. Threshold fluence Fth 0:4 J cm 2 and the volume ablation rate was measured to be 30 < V < 450 mm per pulse in the fluence range 1:4 < F < 21 J cm . The presence of helium avoids gas br...
