FemtoFiber CARS

Ultracompact laser system for label-free nonlinear microscopy (CARS / SRS)

  • Fixed frequency pump laser at 780 nm or 1050 nm
  • Tunable or broadband Stokes lasers covering 488 - 1400 nm
  • Adjustable timing between pump and Stokes laser
  • SAM mode locking, PM fiber based MOPA system
  • Robust and reliable design, push-button operation
  • Free beam output

Coherent Anti-stokes Raman Spectroscopy (CARS) and Stimulated Raman Scattering (SRS) are powerful and label-free techniques for chemical identification of molecules by their characteristic vibrational and rotational modes. TOPTICA provides a variety of pump and Stokes laser configurations for CARS and SRS covering the entire fingerprint region from 450 – 12500 cm-1. The pump and Stokes laser are optically synchronized and their relative timing can be adjusted using a built-in optical delay.
