Introduction

The Y-Fi™ OPA is KMLabs’ vertically integrated, collinear optical parametric amplifier pumped by a Y-Fi™ HP. The class leading pulse duration of the 1035 nm centered Y-Fi™ HP results in both a stable, coherent white light seed source and an exceptionally high conversion efficiency into the short-wave (1350-1800 nm) and mid-wave (2.4 – 4.5 μm) infrared.

Features

  • Compressible in bulk media to < 50 fs pulse
  • Market leading footprint:  40.6 x 30.3 x 11.6 cm
  • Tunable repetition range 1-2 MHz
  • > 15% conversion efficiency with up to 350 mW in the Signal and 100 mW in the Idler
  • <1% shot-to-shot pulse energy deviation in Signal
  • Pulse durations < 50 fs
  • Excellent beam quality: M2 typically <1.4
  • Intuitive control GUI including wavelength and pulse optimization
  • Combination of clean (low pedestal) short pulses and high energy gives higher peak intensities for nonlinear processes

Applications:

  • Short-wave infrared (SWIR) supercontinuum generation
  • Mid-wave infrared (MIR) supercontinuum generation
  • Three and Four photon excitation fluorescence microscopy
  • Spectroscopy
  • Pump probe experiments
  • Tip-enhanced mid-wave infrared nanoscopy and nanospectroscopy
  • Retina safe coherent Raman scattering (stimulated Raman scattering, coherent ant-Stokes Raman scattering, Impulsive stimulated Raman scattering, etc.)
