Newport has introduced the WEU-02, a wavelength extension unit that can be configured for use in various spectroscopy, imaging and pump-probe applications.

The WEU-02 is designed to expand the capability of femtosecond lasers.

It can also be integrated into two-photon microscope setups to add modalities for enhanced imaging capabilities.

The design of the WEU-02 allows the fundamental beam to pass through, preserving the beam path and tuning range of the pump source.

A portion of the fundamental can be sent to a photonic crystal fibre (PCF) to be converted to a broadband super-continuum.

This light can then be recombined with the remaining fundamental for use in pump-probe and multimodal spectroscopy and microscopy experiments.

This super-continuum can be used as a stokes beam to add broadband coherent anti-stokes Raman scattering (CARS) spectroscopy and microscopy capabilities around 3,000cm-1 in existing setups utilising two-photon excited fluorescence (TPEF) and second harmonic generation (SHG).

User controls include a thumbwheel to either maintain the fundamental for two-photon imaging or selectively split to add pump-probe and multimodal capability.

Thumbwheels are also used to independently control the attenuation of the fundamental beam, the input to the PCF and the output stokes beams.

Two-position slide controls allow the user to narrow the bandwidth to 3nm around an 800nm pump or to select whether or not to recombine the pump and stokes.

A micrometer is used to fine-tune the timing of the two beams in order to overlap them temporally.
