K2 Photonics
Pump–probe without the delay line
High-performance pump–probe measurement traditionally needs mechanical delay stages or complex synchronisation electronics, which makes setups bulky, slow and error-prone. K2 Photonics builds compact femtosecond lasers with dual-comb architectures that remove the delay stage entirely. Paeonia represents K2 Photonics in Asia.
Why it is different
- Optical delay sweeps are obtained without moving parts, enabling fast scanning over extended delays.
- Shared-cavity architecture and correlated noise properties ensure femtosecond-level timing precision.
- Eliminating mechanical delay stages dramatically simplifies system complexity and size.
- Solid-state lasers offer ultra-low relative intensity noise, enabling sensitive measurement even at high frequencies.
- A 60 MHz single-cavity ASOPS laser can scan up to roughly 20 ns of optical delay at high speed.
