Light Conversion's TOPAS-white is a high energy two amplification stage non – collinear OPA (NOPA) with built in pulse compressor. A non – collinear pumping scheme of an OPA is used when the collinear approach reaches its limits in respect to broad spectral bandwidth and/or extremely short pulses (< 20 fs). The basic principle of operation of NOPA relies on parametric amplification of chirped signal produced by supercontinuum (white-light) generation. The non-collinear geometry is used due to broad amplification bandwidth in the visible spectral range.
TOPAS-white has a unique optical setup, which allows pumping the device with more than 200 μJ of energy and achieving more than 60 μJ of output at 550 nm.
- Pulse duration down to 15 – 20 fs
- High energy visible output (> 60 μJ @ 550 nm)
- Tuning range from 250 nm to 1000 nm, computer controlled
- Built in pulse compressor
- High output stability throughout the entire tuning range

Pump pulse duration and wavelength affects the specifications. Check the specifiaction with us if the wavelength or the pulse duration differ from above values.
TOPAS‑White output energy scales up linearly in 0.3 – 1 mJ range, provided the device is installed and optimized for a particular pump energy (the device has to be re-optimized for optimal performance should the pump energy change more than ±10 % from the installation value).
