The K2-1000-mini is a compact ultralow-noise 1 GHz femtosecond laser engineered for advanced spectroscopy, precision metrology, nonlinear imaging, and optical frequency comb applications. Designed as a turnkey ultrafast laser platform for OEM integration and research environments, the system combines high output power, ultrashort pulse generation, and exceptional timing stability in a compact all-in-one architecture.

The laser is available as both a traditional mode-locked femtosecond oscillator and an optional dual-comb source capable of generating two highly correlated pulse trains from a single cavity. This architecture enables highly stable dual-comb spectroscopy, precision ranging, and pump-probe measurements without the complexity typically associated with multi-laser synchronization systems.

Operating at a 1 GHz repetition rate with output power exceeding 1.5 W and pulse durations below 200 fs, the K2-1000-mini is optimized for applications requiring low relative intensity noise (RIN), ultralow timing jitter, and high signal-to-noise performance. The platform is suitable for nonlinear microscopy, supercontinuum generation, amplifier seeding, gas sensing, time-resolved spectroscopy, and frequency comb metrology.

Additional configuration options include sub-100 fs pulse operation, fiber-coupled output, wavelength extension via OPO systems, and passively cooled low-power versions for integration into compact photonic instruments.

Why Single-Cavity Dual-Comb Technology?
Traditional dual-comb systems typically require synchronization of two separate mode-locked lasers, increasing system complexity and sensitivity to environmental drift. The K2-1000-mini simplifies this architecture by generating two highly coherent pulse trains from a single cavity, enabling improved mutual coherence, reduced timing drift, and enhanced stability.

This approach supports compact, robust, and easier-to-integrate dual-comb systems for spectroscopy, ranging, and ultrafast measurement applications while reducing synchronization overhead and improving measurement reliability.
