TOPAS-PRIME is a collinear femtosecond optical parametric amplifier (OPA) designed for use with Ti:Sapphire lasers.

TOPAS-PRIME accepts pump pulse energies of up to 3.5 mJ at 20 – 70 fs (up to 4 mJ at 70 – 200 fs).
TOPAS-PRIME-PLUS accepts higher pump pulse energies, up to 6 mJ at 70 – 200 fs.

Both models include wavelength extension options, offering a tunable range from 189 nm to 20 μm.

Ultrafast (20–70 fs)

Specifications notes

TOPAS-PRIME and TOPAS-PRIME-PLUS specifications are given for the following pump laser parameters:

Wavelength: 800 nm
Pulse energy: 1 mJ
Repetition rate: 1 kHz
Pulse duration: 30 – 40 fs
Beam profile: Gaussian

Note 1: Specifications depend on the pump wavelength and pulse duration. If these differ from the values listed above, contact sales@lightcon.com.

Note 2: TOPAS-PRIME output pulse energy scales linearly within the 1 – 5 mJ range, provided the device is installed and optimized for a specific pump energy. Re-optimization is required if the pump energy changes by more than 10% from the installation value.

Tuning curves

CEP stabilization of Idler

The Idler of TOPAS (1600 – 2600 nm) is passively carrier-envelope phase (CEP) locked due to the three-wave interaction process. However, a slow CEP drift may occur as a result of pump beam pointing fluctuations or changes in environmental conditions. This drift can be compensated by employing an f-2f interferometer combined with a feedback loop, which controls the temporal delay between seed and pump in the power amplification stage of TOPAS-PRIME and TOPAS-PRIME-HE.
