The HYPUS ™ - HYPer Spectral Ultrafast Source
OPA-free wavelength tuning
HYPUS technology provides a unique OPA-free approach to wavelength tuning. It delivers six optically synchronized channels spanning 200 nm (UV) to beyond 12 µm (mid-IR), achieving pulse energies exceeding 5 µJ per channel without the need for optical parametric amplification.
Channel | Tuning range | Energy, uJ | Pulse duration, fs | Generation method |
|---|---|---|---|---|
(1) UV | <200 nm - 450 nm | 5-10 µJ | <6 fs | Resonant Dispersive Wave |
(2) Visible | 450 nm - 650 nm | >100 µJ | 10 fs and 50 fs options | Second Harmonic Generation |
(3) near IR | 750 nm - 1300 nm | 1300 µJ | 7 fs | Spectral Broadening |
(4) near IR telecom | 1.4 µm - 1.8 µm | 5 µJ | 150 fs | Idler Generation |
(5) mid IR | 3 µm - 4.5 µm | 5-12 µJ | 90 fs | Difference Frequency Generation |
(6) mid IR | 4.5 µm - >10 µm | 10-22 µJ | 150 fs | Difference Frequency Generation |
(W) White light | 300 nm - 900 nm | up to 60 µJ | Spectral Broadening |

OPA Technology
FOPA: Frequency Domain Optical Parametric Amplification
Employing multiple, individually tunable nonlinear crystals in the Fourier plane means:
- Simultaneous upscaling of peak power & spectral bandwidth.
- Gain tailoring by spatial pump beam shaping.
- Upscaling not limited by crystal aperture.
- Transform limited ps pulses in Fourier plane.
- No extra stretcher / compressor required.
- Only “small” gratings required in the 4f setup.
- Can be pumped by stretched Ti:Sa pulses or ps Yb lasers.
Deep UV pulse shaping
Decomposing a broadband pulse into single wavelengths prior to nonlinear interaction:
- Reduces intensity.
- Avoids mixing of wavelenghts.
- Permits linear transfer of arbitrairy phase functions.
- Enables deep UV pulse shaping down to 207nm - just with a conventional shaper prior to the Ti:Sa amplifier.
