ShapeShifter Transient Absorption Spectrometer

Pump/probe transient absorption spectrometer

ShapeShifter is a state-of-the-art pump/probe transient absorption spectrometer research tool that can be configured to perform experiments using many different types of nonlinear processes with transient absorption as the default option.

It is designed, fabricated and tested using field-proven components from a single manufacturer, thereby minimizing your technology adoption risk. ShapeShifter is capable of meeting your current needs while retaining the flexibility to add options1 that include pulsewidth as short as 15 fs2, a large range of pump and probe wavelengths (e.g. sub-200 nm to beyond 10 microns) with decay times ranging from sub-30 femtoseconds to nanoseconds, and at user-selectable repetition rates that are variable from single-shot to multiple kHz. It can be used to explore heat-affected-zone and embrittlement-free structuring in a wide variety of materials using pulse widths that are variable from 30 fs to 10 ps.

ShapeShifter begins with the field-proven Clark-MXR Model CPA-series of patented, fiber-oscillator-seeded, Ti:Sapphire amplifiers3 The output beam of the Model CPA can be split into as many as seven beams to pump as many as seven tunable, non-collinear OPAs (NOPAs). Or you can use one beam to generate multiple continua and/or you can microstructure materials to create features smaller than 1 micron. Clearly, ShapeShifter™ is the ideal tool for a user facility.

Why limit your future options when ShapeShifter™ offers you unmatched flexibility to go where your research takes you?
