Description

Frequency comb technology makes direct measurement of absolute optical frequencies possible. The FC1500 Optical Frequency Comb is a compact, portable and flexible fiber-based femtosecond frequency comb system. With the Extension Packages M-VIS and M-NIR the system is capable of providing at the same time a source for frequency metrology in both the visible (500-1050 nm) and the near-IR regions (1050-2100 nm) of the spectrum. A wide range of optional units enables us to tailor this versatile system to customer specific metrology solutions.

Options

  • EOM-Phase Electro-optic Phase Modulator

    Product Code: EOM-Phase

    Integrated into the laser cavity; allows high-performance phase locking to an optical reference by increasing the bandwidth of the repetition rate lock by more than an order of magnitude. With this EOM option sub-Hz line widths can be achieved. Required for high-performance phase locking to an optical reference.

  • M-NIR Extension Package

    Product Code: M-NIR

    Extends the stabilized comb spectrum to a range of 1050 - 2100 nm with free-space output port and >200 mW average power. The measurement port can be optimized independently from the CEO frequency stabilization.

  • M-VIS Extension Package

    Product Code: M-VIS

    Extends the stabilized comb spectrum to the 500-1050 nm range with free-space output port and >60 mW average power.

  • HMP High Power Measuring Port

    Product Code: HMP

    Provides stabilized comb light with highest power at customer-defined wavelengths for high precision measurement of lasers with low power levels (<100 µW). A minimum of 3 mW average power in a 3 nm window is provided at the central wavelength specified by customer. Available for 1050 - 2100 nm (HMP-NIR), or 525 - 1050 nm (HMP-VIS). The output is fiber coupled and optional available as free space.

    For 390 - 400 nm (HMP-UV) a minimum of 1 mW average power in a 1 nm window is provided. the output is free space.

  • P250 PM PULSE EDFA Erbium-doped Fiber Amplifier

    Product Code: P250 PM PULSE EDFA

    All polarization maintaining (PM) amplifier delivers intense near infrared pulses with >350 mW at 1560 nm. Several amplifiers can be added for multiple measurement ports.

  • M-780 High Power Measuring Port at 780 nm

    Product Code: M-780

    Output provides stabilized comb light with highest power at 780 nm.
    Contains an amplifier and subsequent frequency conversion, delivering a minimum of 150 mW average power with a central wavalength in the range of 780-800 nm. The output is free space and optional available as fiber-coupled.

  • BDU Beat Detection Unit

    Product Code: BDU

    Generates and measures the beat signal between the frequency comb and an external continuous wave (cw) laser. Available for various spectral ranges, with free space or fiber-coupled optics, and matched to the customer's laser.
