New TOPAS White high power non-collinear femtosecond OPA

PRINT

BACK

The TOPAS White is a non-collinear OPA (NOPA) developed for high conversion efficiency of ultrashort pulse operation in the UV and visible range. It utilises 100+ femtosecond pulses to generate 10-30fs output. In the visible wavelength range, the TOPAS White gives high energy output, typically more than 40µJ.

The TOPAS White is a device that is pumped by 100 - 200fs pulses from an amplified Ti:Sapphire laser system and provides tunability in the visible range along with pulse compression. The pump pulses are tilted to match the signal for higher applicable pump energy and conversion efficiency. Internal efficiency of the OPA of over 30% and signal pulse energy over 40µJ has been achieved.

TOPAS White key features:
• Pulse duration less than 20fs possible
• High energy visible output (more than 40 microjoule)
• Tuning range 480 – 1600nm
• Tuning range 250 – 450nm with SHG
• Pulse duration and bandwidth control
• Fully computer controlled tuning
• Compact and stable design
• High output stability
• Flexible phase control using an adaptive mirror

The TOPAS systems are manufactured in Lithuania by Light Conversion and are marketed worldwide by Quantronix. Photonic Solutions are the distributors in the UK for the Quantronix range of products. As well as Quantronix, Photonic Solutions are the distributor for a variety of other companies offering a range of Lasers and laser systems, detectors and spectroscopy equipment.
