Technical content

Compact Pulse Compressor for Vitara The CPC-II pulse compressor accessory for Vitara is designed to deliver near transform-limited pulses at the target sample. The CPC-II achieves this by introducing continuously variable negative Group Delay Dispersion (GDD/prechirp) to precisely compensate for normal dispersion of downstream optics. Using chirped-mirror technology, the CPC-II provides an ultra-compact footprint for maximum ease-of- use and the input and output beam ports are in line to enable simple experimental setups. FEATURES & BENEFITS

  • Maximizes peak power for enhanced nonlinear processes
  • Coarse and fine GDD control for precise pulse compression
  • In-line input and output ports for easy alignment
  • Pre-compensates for positive dispersion from downstream optics
  • Ultra-compact footprint

APPLICATIONS

  • Second Harmonic Generation
  • THz Generation
  • Coherent Anti-Stokes Raman Scattering (CARS)
  • Multiphoton Imaging
  • Non-Linear Optics
