  • Toptica Locking Electronics: FALC & PFD Push-button phase-frequency lock

    Toptica Locking Electronics: FALC & PFD Push-button phase-frequency lock

    The DFC locking electronics consisting of the Phase Frequency Detector (PFD) and FALC 110 provides high-end phase frequency locking for comb applications.

  • Toptica Difference Frequency Comb (DFC): Compact, robust, high-end and convenient

    Toptica Difference Frequency Comb (DFC): Compact, robust, high-end and convenient

    TOPTICA’s frequency comb product line uses their proprietary CERO-technology which is based on Difference Frequency Generation (DFG). It is inherently fCEO-stable and combines high robustness, high-end performance and a convenient user-interface in a compact format.

  • Toptica DFC SEED Low-noise OPCPA seeder

    Toptica DFC SEED Low-noise OPCPA seeder

    The DFC SEED unit is dedicated for OPCPA and high power amplifier seeding that require phase-stable ultrashort laser pulses at 1560 nm and 1030 nm or 1950 nm. It combines an outstanding passive CEP stability which challenges the best Ti:sapph lasers with the convenience and robustness of a fiber laser. Long-term drifts of the CEP that are caused by a subsequent amplifier chain can be compensated through a dedicated feedback channel. The repetition rate frep of the DFC SEED can be synchronized to any appropriate reference.

  • Toptica DFC SDL Frequency-comb-stabilized laser system

    Toptica DFC SDL Frequency-comb-stabilized laser system

    TOPTICA's offset-free frequency comb DFC (Difference Frequency Comb) and tunable cw diode lasers (DL pro) can be combined into easy-to-use laser systems delivering frequency-stable cw-output at any wavelength between 420 nm and 2200 nm. A complete laser system contains a DFC CORE, wavelength extensions (DFC EXT), cw diode lasers (DL pro), beat units (DFC BC, DFC MD), all necessary stabilization electronics, a wavelength meter (High Finesse), RF-reference, counter, spectrum analyzer, control server (PC) and user software.

    All these components can now be integrated into a single transportable 19-inch rack. The standard system comes with two frequency stable cw-outputs and all required accessories. The control software runs on an integrated PC acting as server, it can be operated remotely using the client GUI. The laser frequencies can be set manually within the comb extension and DL pro bandwidth and are displayed live by the software.

  • Toptica DFC CORE / DFC CORE+ Low-noise frequency comb

    Toptica DFC CORE / DFC CORE+ Low-noise frequency comb

    The CORE unit of TOPTICA’s Difference Frequency Comb (DFC) consists of a low noise mode-locked oscillator, a fiber-optic amplifier, a nonlinear fiber for supercontinuum generation, a CERO unit for difference frequency generation (DFG) and a fiber-optic pre-amplifier. The DFC CORE provides 4 or 8 fCEO-stabilized outputs at 1560 nm. Each output can seed a user-defined extension as specified on the DFC Extensions section. It comes with integrated radio frequency reference and dedicated frep locking electronics. A beat monitoring unit comprising a laptop and a digital scope with spectrum analyzer mode allows for convenient monitoring and analysis of locking beats.

  • Toptica Difference Frequency Comb (DFC) Inherently CEP-stable modular frequency combs

    Toptica Difference Frequency Comb (DFC) Inherently CEP-stable modular frequency combs

    TOPTICA’s frequency comb product line is a modular system that supports a broad variety of applications. Three basic versions of the DFC are available: DFC CORE, DFC CORE+ and DFC SEED. All models use TOPTICA proprietary CERO-technology to achieve an unprecedented low-noise performance.
