Class 5 Photonics products

The White Dwarf TPA is a specialized femtosecond laser system dedicated to maskless nanolithography through two-photon absorption (TPA). This system stands out due to its remarkable average power output and high repetition rate, crucial for advancing nano-resolution capabilities and boosting production speeds in nanofabrication. Its compact, single-box design ensures robust integration into existing setups, while the advanced pulse control technology allows operators to finely tune pulse intensity and dispersion according to the specific requirements of their samples, resulting in enhanced nanofabrication productivity. Key features of the White Dwarf TPA include high power stability over extended periods, with a spectrum centered at 800 nm and pulse durations measured at 40 fs. It delivers over 8 W of average power at microjoule pulse energies, providing a distinct advantage over conventional systems that either compromise on power or pulse duration. The combination of high peak power and rapid repetition enhances productivity in TPA applications, supported by advanced optical strategies like spatial multiplexing.
