Description
The K2-1000 is a high-power 1 GHz dual-comb femtosecond laser system engineered for advanced spectroscopy, precision ranging, nonlinear optical studies, and optical frequency comb applications. Based on a novel single-cavity dual-comb architecture, the system generates two highly coherent femtosecond pulse trains with slightly different repetition rates, enabling ultrafast optical delay scanning and high-precision heterodyne measurements without the complexity of conventional multi-laser synchronization systems.
Designed as a high-performance platform for scientific research and advanced photonic instrumentation, the K2-1000 combines ultrashort pulse generation, high average power, ultralow relative intensity noise, and exceptional timing stability in a compact turnkey architecture optimized for dual-comb spectroscopy and ultrafast optical measurements.
Operating at a 1 GHz repetition rate with output powers exceeding 2 W per beam and pulse durations below 100 fs, the system delivers high power per comb line for demanding spectroscopy and nonlinear optics applications. The shared-cavity design provides passive mutual coherence and sub-cycle relative timing jitter in free-running operation, eliminating the need for complex high-speed locking electronics and optical amplification.
The K2-1000 is ideally suited for dual-comb spectroscopy, precision ranging, gas sensing, THz time-domain spectroscopy, pump-probe measurements, nonlinear optical studies, supercontinuum generation, and high-speed time-resolved spectroscopy.
Available options include integrated second-harmonic generation (SHG), wavelength conversion via optical parametric oscillator (OPO), supercontinuum generation configurations, ultrabroadband operation, fiber-coupled outputs, and stabilized repetition-rate control.

Why Single-Cavity Dual-Comb Technology?
Traditional dual-comb spectroscopy systems typically rely on two independent mode-locked lasers requiring complex synchronization electronics and active stabilization. These architectures increase system complexity, footprint, and sensitivity to environmental drift.
The K2-1000 simplifies this approach by generating two highly coherent femtosecond pulse trains within a single shared optical cavity. This architecture passively stabilizes the relative intensity, timing, and phase noise between the combs while eliminating the need for high-speed locking electronics and optical amplification.
The result is a more compact, robust, and stable dual-comb spectroscopy platform capable of ultrafast optical delay scanning, high-resolution spectroscopy, and precision ranging with improved noise performance and simplified system integration.
