Wavelength Extender

Introduced by Spectra-Physics to their line of nonlinear microscopy and spectroscopy application solutions, the SCG-02 wavelength extender is specifically designed as a modular solution for supercontinuum generation, when used with the company’s Tsunami, MaiTai and DeepSee femtosecond Ti:Sapphire lasers as well as MaiTai ultrafast oscillators. The laser input is split into two parallel beams: the fundamental pump, and parallel, unfiltered broadband supercontinuum. This flexibility allows for both the external selection of particular spectra of interest, and the independent use or recombination of both beams. The fundamental beam passes through an integrated attenuator to enable precise control of the output power. The wavelength extender is factory preassembled and pre-aligned and can easily be integrated into ultrafast light sources to provide turnkey solutions for multimodal spectroscopy and imaging. It can be used with two-photon microscopes for additional modalities and enhances pump-probe imaging and spectroscopy capabilities. Features include manual controls to attenuate fundamental throughput and to generate parallel, broadband supercontinuum output. The robust and reliable device preserves the beam path and the tuning range of the pump source.
