Newport’s UPM Series Ultrashort Laser Pulse Measurement Device is able to completely characterize the pulse, yet maintains experimental simplicity as opposed to the traditional autocorrelator. It also yields the most complete measurement technique of ultrashort laser pulses ever. The Newport UPM device operates alignment-free, requires only a few simple optical elements, and features an operating range that includes that of most ultrafast Ti:Sapphire and solid-state lasers and amplifiers.
Unlike other pulse-measurement devices, Newport’s UPM is very easy to use. It comes pre-aligned, and aligning your beam into it is easy. Simply set the switch for the UPM to measure the beam spatial profile, connect the camera output to a video monitor or frame-grabber, send a fraction of your beam into it, and walk your beam to the center of the camera. Then switch to the temporal mode and the UPM is already generating Frequency-Resolved Optical Gating (FROG) traces of pulses!
The UPM Series yields the pulse intensity and phase vs. time, spectrum and spectral phase with great accuracy and reliability, making no assumptions about the pulse. The UPM device will not become misaligned for the simple reason that there are no alignment knobs to turn! And it's very tolerant to small displacements ...

The UPM device will not become misaligned for the simple reason that there are no alignment knobs to turn! And it's very tolerant to small displacements of the input beam.
In addition, the UPM Series also simultaneously measures spatio-temporal distortions, such as spatial chirp and pulse-front tilt, which occur in most ultrashort pulses but are almost never measured. The UPM Series is the most accurate diagnostic tool ever developed for these distortions and the only commercially available device capable of measuring them. In addition, it also yields the beam spatial profile and the pulse absolute wavelength; and with one of the available FROG pulse-retrieval software packages, it does all this in real time.
