The Reef-RTD real-time autocorrelator is an advanced tool designed for the precise measurement of femtosecond and picosecond pulse durations. With a variety of models available, this autocorrelator caters to different wavelength ranges, ensuring flexibility for diverse experimental needs. The Reef-RTDM model stands out by combining multiple ranges through the use of three interchangeable photodetectors and optics, offering a comprehensive solution for those requiring extensive wavelength coverage. For specialized requirements, two separate ranges can be accommodated upon request, making this device adaptable to a multitude of laser systems.

The device is user-friendly and integrates seamlessly with a PC via a USB interface, supporting Windows operating systems. It comes equipped with sophisticated software that allows users to visualize, store, and export pulse duration data in .txt or .dat formats. Real-time calculations of the autocorrelation function and the full width at half maximum (FWHM) pulse duration in femtoseconds are displayed, with Gaussian or sech2 fitting options available. Additionally, users can observe the intensity function and utilize the statistical viewer feature to compare data from different pulse measurements.

Compact and efficient, the Reef-RTD's small dimensions (132x123x118 mm) make it an ideal fit for experimental setups with limited space. An optional fiber input enhances its versatility, allowing for quick and reliable pulse duration measurements in various optical fibers while maintaining its free-space measurement capabilities. This makes the Reef-RTD an indispensable tool for researchers and professionals working with femtosecond and picosecond oscillators.
