SRS Laser Replacement

Description

Replacement of SRS laser (due Sept 25): PicoEmerald FT with upgraded electronics to improve speed, productivity and sensitivity Lot 1: Replacement of SRS laser (due Sept 25): PicoEmerald FT with upgraded electronics to improve speed, productivity and sensitivity. Tuning speed: 1.5 s for a random tuning step, up to 100x faster than previous generation picoEmerald S we currently have at NPL. Highly improved signal-to-noise ratio mainly due to the reduction of the laser repetition rate leads to 10x faster image acquisition compared to picoEmerald S. This two-colour turnkey system ideal for stimulated Raman microscopy up to video rate speed as it offers perfect temporal and spatial overlap of exit beams; tuneable between 660 nm and 2340 nm which translates to 210 cm-1 to 5450 cm-1 energy difference (currently we can go 660 cm-1 to 4500 cm-1 ) providing the opportunity to analyse also a variety of materials that we are not capable of right now; 2 ps pulses with 10 cm-1 spectral width providing a similar spectral resolution to our current device; extremely low noise compared to all-fiber laser systems; compatible with commercial microscopes and homebuilt setups; active and passive stabilization, ideal for long-term experiments This laser will increase the capacity of our facility but will provide also new capabilities in offering services on dynamic samples.
