Femtoline: optics and crystals for femtosecond lasers

Femtoline is our dedicated line of optics and crystals engineered for ultrashort pulses. We work with the leaders building and using femtosecond lasers — and as one of the strongest suppliers in the market, we can be your partner too.

It's a single, curated entry point for fs-laser builders and users — pulling the right parts from across our whole catalog so you don't have to.

Femtoline components

Six groups of fs-ready components — laser optics and crystals designed for broadband Ti:Sapphire and Yb:KGW/KYW fundamental and harmonic wavelengths, tuned to preserve pulse duration.

Femtoline Mirrors

Low-GDD and dual-line laser mirrors, harmonic separators and output couplers for ultrashort pulses.

Femtoline Lens Kits

Matched lens kits with broadband AR coatings for fs beam handling and focusing.

Femtoline Polarizing Optics

Thin-film polarizers and zero/low-order waveplates for dual wavelengths.

Femtoline Thin Lenses

Ultrathin AR-coated lenses that minimise dispersion in the beam path.

Femtoline Prisms

Prisms for dispersion control and GVD compensation in fs setups.

Femtoline Nonlinear & Laser Crystals

Ultrathin BBO for SHG/THG of Ti:Sapphire, BBO & LBO for Yb:KGW/KYW, AgGaS₂ for DFG, and Femtokits.

Why Femtoline performs

Every part in the line is specified to preserve pulse duration and survive high peak power.

  1. 1

    Low GDD mirrors

    Controlled group-delay dispersion keeps femtosecond pulses short through the beam path.

  2. 2

    Thin AR lenses

    Ultrathin substrates with broadband AR coatings minimise added dispersion.

  3. 3

    GVD compensation

    Prisms and plates manage group-velocity dispersion in your setup.

  4. 4

    Ultrathin crystals

    Thin BBO/LBO/AgGaS₂ for efficient SHG, THG and DFG of fs lasers.
