Ultrafast lasers are a very powerful tool for light microscopy and laser science applications. Femtosecond pulses of light are naturally dispersed when transmitted or reflected by an optic resulting in a reduction in peak power. Quantifying and controlling optical dispersion are important criteria to maintain pulse performance.
Semrock is proud to announce the introduction of the PulseLineTM family of optics that are specifically designed for femtosecond laser applications.
The FS01-S-pol and FS01-P-pol mirrors are >99.2% reflective with quantified and repeatable Group Delay Dispersion (GDD) characteristics. These mirrors are also manufactured using IBS hard coated technology for maximum durability and feature high reflectivity, low dispersion and an exceptionally high laser damage thresholds. Third party measurements using 20ns pulsed light at 1064nm revealed values in excess of 20J/cm2.
They are ideal for applications where femtosecond laser beams need to be guided from the output of the laser head to the sample, and are especially useful in multiphoton microscopy and femtosecond laser spectroscopy. These are ideal for covering the full Ti:S laser tuning range of 680-1080nm.
February 2013 - Semrock have added a line of low-dispersion beamsplitters with four different splitting ratios and for either s- or p-polairsed light. These beamspliiters operate over the tuning range of a Ti:S Ultrafast laser (650-1100nm). Read more in the new 2013 catalogue, download from the Literature tab.
