Orpheus-PS Series - Narrow Bandwidth Picosecond Optical Parametric Amplifier

ORPHEUS-PS is a narrow bandwidth OPA designed for PHAROS pump laser. This device is pumped by the picosecond pulses produced in SHBC-515 narrow bandwidth second harmonic generator, and seeded by white light continuum generated by femtosecond pulses. The system features high conversion efficiency, nearly bandwidth and diffraction limited output and full computer control via USB port.

Description 

Features

  • 210 – 4800 nm tunable wavelength
  • 800 fs – 3 ps pulse duration
  • < 15 cm-1 spectral width (typical)
  • Up to 100 kHz repetition rate
  • Completely computer controlled
  • Built on well known TOPAS-800 OPA basis

ORPHEUS-PS is a narrow-bandwidth optical parametric amplifier, designed for Pharos and Carbide lasers. This device is pumped by the picosecond pulses produced in a second harmonic bandwidth compressor SHBC and is seeded by a white-light continuum generated by femtosecond pulses. This enables very high pulse-to-pulse stability compared to other methods of generating tunable picosecond pulses. The white-light generation module is integrated into the same housing as the amplification modules, enabling even better long-term stability and ease of use. The system features high conversion efficiency, bandwidth- and diffraction-limited output, and full computer control.

Part of the laser radiation can be split to simultaneously pump a femtosecond OPA, providing broad-bandwidth 630 nm – 16 μm tunable pulses, giving access to the complete set of beams necessary for versatile spectroscopy applications such as femtosecond stimulated Raman spectroscopy (FSRS) and sum-frequency generation (SFG) spectroscopy.

Second Harmonic Bandwidth Compressor SHBC-515

This device is required to pump Orpheus-PS with PHAROS / CARBIDE femtosecond laser. It is dedicated for the formation of narrow bandwidth picosecond pulses from broadband output of ultrafast laser.

SHBC enables the creation of versatile optical setups which use fixed-wavelength or tunable narrow-bandwidth picosecond pulses in combination with tunable-wavelength broadband femtosecond pulses. In particular, such setups are of interest in sum-frequency generation (SFG) spectroscopy and femtosecond stimulated Raman spectroscopy (FSRS).
