FAQ
The White Dwarf TPA delivers more than 8 W of average power at microjoule-level pulse energies, while maintaining an ultrashort pulse duration of 50 fs in a compact system. In contrast, common laser systems used in TPA provide either only a few Watts at nanojoule pulse energies, or higher power, but with few-100 femtoseconds. Thus, the White Dwarf TPA provides the highest peak power at high repetition rate to drastically improve productivity in TPA maskless nanolithography.
Typically, various multiplexing strategies are being implemented in the materials processing system. Those include spatial multiplexing using microlens arrays, light beads multiplexing, or advanced fast-scanning techniques. Contact us for more information.
