news 
datasheet

ORPHEUS-F is a collinear optical parametric amplifier (OPA) of white-light continuum pumped by femtosecond Ytterbium based laser PHAROS and capable of operating at repetition rates of >1MHz. This OPA combines the short pulse durations produced by a non-collinear OPA and wide wavelength tuning range offered by collinear one.


 
FEATURES
 
  Combines the best features of collinear and non-collinear OPA
  Pulse duration compressible down to <40 fs
  Adaptable to different pump pulse energy,repetition rate up to 1 MHz
  Variable output bandwidth
  Full computer control via USB port and dedicated software
 
Description:

 

ORPHEUS-F is a collinear optical parametric amplifier of white-light continuum pumped by femtosecond Ytterbium based laser amplifiers. This OPA combines the short pulse durations that are produced by a non-collinear OPA and wide wavelength tuning range offered by collinear version. Parametric amplification is performed in two stages. The first nonlinear crystal (BBO) is non-collinearly pumped with the second harmonic of pump laser at 515 nm and seeded with a white light continuum, producing broad bandwidth tunable output in 650 nm – 900 nm wavelength range. The second nonlinear crystal (type 1 BBO/LBO) is again pumped by the SH of pump, but in a collinear configuration. The output of the second stage is a Signal wave tunable in the range of 650 nm – 900 nm, and corresponding Idler at 1200 nm – 2500 nm. Both beams exhibit a broad spectrum, with typical bandwidth reaching 300 – 600 cm-1 at some wavelengths. The Signal beam can be easily compressed with a simple prism-based setup down to <60 fs in most of the tuning range, while Idler is compressed in bulk material down to 40 fs – 90 fs depending on wavelength.

Before amplification white light continuum pulse can be dispersed by inserting different amount of glass in the beam path. This makes it possible to limit the output bandwidth to some extent (up to 2 – 3 times) without losing any output power. By comparison, standard ORPHEUS device uses spectral narrowing to produce bandwidth-limited 200 fs – 300 fs duration pulses directly at the output, with extended Signal/Idler tuning range and options to generate ultraviolet and mid-infrared light. Our non-collinear ORPHEUS-N-2H device produces even broader bandwidths, compressible down to <20 femtoseconds, but limits the tuning range to 650 nm – 900 nm. This places the performance of ORPHEUS-F configuration in between our other solutions.
