BSI produces the only instruments capable of automated pulse compression. This means that with a simple click of a button the system measures pulse dispersion (including high order) and compensates the measured dispersion in order to obtain transform limited pulses, typically within less than 1% of the theoretical Fourier transform limit. This process is completed within less than a minute (depends on the system resolution and laser characteristics) and involves no moving parts.
The immediate advantage is that without the need of a laser expert, the femtosecond laser performs at its theoretical best. This is especially important because optics used to deliver the laser beam to the sample (lenses, mirrors, and microscope objectives) can introduce significant dispersion. Our instruments eliminate this dispersion automatically.
For users interested in controlling the laser pulses (phase, amplitude or polarization) the systems are able to control these parameters with one important advantage. That the pulses are first compressed to the transform limit, that is, that the pulses have a flat phase at the sample. This is very important in order to achieve reproducible results. The user then has the option to introduce essentially any phase amplitude or polarization.
Our systems are compatible with any femtosecond laser, any wavelength and any energy with little or no customization. Contact one of our Application Scientists to determine how one of our instruments could improve your results and open a world of possibilities.
