FROGscan

Our FROGscan Standard system is versatile, adaptable and easy to use. With our FROGscan Standard, you can tweak a laser system or measure highly chirped pulses to calculate the amount of dispersion compensation you might need for recompression. You can measure a short pulse that has been chirped out to several picoseconds, and measure pulses as short as 12 fs in real-time. FROGscan Standard measures the most complex pulses of any pulse measurement system on the market.

FROGscan Standard is a workhorse pulse measurement system. We designed and built it to be used day in and day out for all of your pulse measurement needs.

Whether you are tweaking up a laser system or measuring shaped pulses, FROGscan Standard is just right for your needs. What happens if you need a new wavelength? You simply change the SHG crystal and spectrometer to adapt it to your needs. Crystal changing requires no realignment; it is kinematically mounted and the software reads the crystal specifications. Our FROGscan Standard pulse measurement system can measure pulses from 450 nm to over 2000 nm and from 12 fs long to 10’s of picoseconds.* The high speed translation stage coupled with our VideoFROGscan software (included with the system) means that FROGscan Standard can make pulse measurements in real-time at nearly 4 Hz (32 x 32 grid, ~115 spectra/second, 1.8 Hz for 64 X 64 grid).

Our FROGscan Standard is pictured above. Your laser beam enters from the right through an alignment iris. Optional alignment cameras make aligning the system a snap. A beam splitter sends one pulse replica though a fixed delay. The other replica is sent to a high-speed, high accuracy optical delay line. Both beams are focused into a second harmonic generation crystal. The SHG signal from the pulse overlap region is spectrally resolved using an Ocean Optics Flame spectrometer. The software reads the spectrometer specifications from the spectrometer. The software is backwards compatible to USB2000+ and USB4000 spectrometers.

Do not be fooled by its simplicity, however. Because of your seamless ability to change the time span of a scan, a single configuration of our FROGscan Standard can replace 3 or more competing FROG devices. The added dynamic range of the 16-bit data acquisition allows highly structured pulses and high order phase distortions to be measured.

Our device can also accomplish measurements competing devices cannot do. For example, just try to measure a 20 fs laser pulse chirped to 400 fs with competing FROG devices. You can’t. The combination of the pulse length and the bandwidth cannot be handled by any device that uses the SHG crystal as the dispersive element. FROGscan Standard makes such a measurement easy. Time scan ranges can be changed on the fly, and wavelength too – all by software control. USB connections to your computer are all that is required. Since the software is included, it is the best value available for pulse measurement.
