Features
- Two independently tunable outputs
- 240 nm – 20 μm tuning range, in each channel
- > 25% conversion efficiency
- High output stability
TOPAS-TWINS consists of two independently tunable optical parametric amplifiers (OPAs) integrated into a single housing. Both OPAs share the same white light source to provide excellent stability of both outputs, and CEP stabilized mid-IR pulses in a tuning range of 4.5 – 15 μm.
Both OPAs come with wavelength extension options, covering the wavelength range from 240 nm to 20 μm. Output specifications for each OPA are the same as those of TOPAS-PRIME. The maximum pump pulse energy depends on the pulse duration; see the specifications for more details.
TOPAS-TWINS specifications are given for the following pump laser parameters:
- 800 nm wavelength
- 1 mJ pulse energy
- 1 kHz repetition rate
- 30 – 40 fs pulse duration
- Gaussian beam
Note 1: Specifications are given for a single TOPAS-TWINS channel.
Note 2: Specifications depend on pump wavelength and pulse duration. If they differ from the values above, contact sales@lightcon.com.
Note 3: Output pulse energy of each TOPAS-TWINS channel scales linearly in 1 – 4 mJ range, provided the device is installed and optimized for particular pump energy. The device has to be re-optimized if the pump energy changes more than 10% from the installation value.
- Maximum repetition rate for DFG1 (NDFG1) option is 1 kHz.
- Contact sales@lightcon.com for higher pump power options.
- Normalized to average pulse energy, NRMSD.
- Normalized to average pulse duration, NRMSD.
- M2 specification valid for Gaussian beam.
- Normalized astigmatism – difference of the waist positions, divided by Raleigh length.
- Normalized to Gaussian or Super-Gaussian fits, NRMSD.
- NRMSD, full angle.
- Optional external telescope can be ordered for the beam diameter of 9.5 – 28 mm.
- Normalized to average pulse energy, NRMSD.
- Output ports are wavelength-dependent.
- Maximum pump repetition rate – 1 kHz. Limited crystal life time of 1000 – 2000 h.

Not available in collinear configuration.
