The MIKS series are ready-to-integrate add-on modules that shorten pulses from industrial femtosecond/picosecond lasers via nonlinear spectral broadening in multipass cells followed by compression with dispersive mirrors. They achieve compression factors of 5–45x with high transmission (>80–90%) and require minimal setup changes. Designed for 24/7 industrial reliability.
Depending on the model and input:
MIKS1_S / MIKS1_M / MIKS1_L → <45 fs (often 30–45 fs demonstrated)
MIKS12 / MIKS12_UP → <15 fs or 7–10 fs (few-cycle regime). Actual results depend on input pulse (100 fs–3 ps), energy, and laser (e.g., <10 fs shown with FLINT laser).
Compatible with nearly all commercial ultrafast lasers, including Yb-based systems. Proven compatibility and showcases include:
Transmission is typically >90% for single-stage models (e.g., MIKS1_S) and >80% for higher-compression variants (e.g., MIKS12). This high efficiency minimizes power loss while achieving strong pulse shortening.
Most models are single-stage (one multipass cell + dispersive mirrors) for simplicity and robustness, delivering 5–15× compression. Higher factors (15–50x, few-cycle pulses) use cascaded/multipass designs (e.g., MIKS12 series). Custom multi-stage options available on request.
Yes—MIKS modules are designed as add-on units with simple optical input/output. Frequently, as with micromachining setups using F-Theta lenses, dispersion pre-compensation is necessary, and the pulse duration measurement after the F-Theta lens is necessary too. Many users install remotely with our guidance.
The modules handle a wide range of repetition rates typical for industrial femtosecond lasers (kHz to MHz), as compression relies on energy per pulse rather than rep rate. Demonstrated with systems from 100 kHz (e.g., Pharos/Carbide) up to higher rates—specify your laser for confirmation.
Yes—two of our multipass cell (MPC) products, MIKS1_S and MIKS1_M are particularly designed for industrial applications. These are compact, sealed boxed where everything is integrated inside the box. Combined with high transmission and rugged, monolithic aluminium housing design, they enable 24/7 operation in industrial settings like micromachining. Both gas-based and solid-state based broadening are available in this case.
Yes—models like MIKS12 and MIKS1_XS routinely deliver 7–10 fs pulses (few-cycle regime) from suitable inputs (e.g., <10 fs demonstrated with FLINT, Pharos and Carbide lasers). This enables applications in nonlinear microscopy, ultrafast spectroscopy, attoscience, or extreme nonlinear optics.
Multipass cells (Herriott-type) offer greater robustness, better power handling, and easier alignment than hollow-core fibers. Our MPC design is insensitive to the beam pointing and beam positioning fluctuations, it has strong, multiple mm, tolerances for the misalignment.
