Description

光学参考系统(ORS-Cubic)能够提供一束具有超窄线宽和短时超高稳定性的单色连续光输出。系统主要包括一台稳定锁相到超高精细度光学腔的连续激光器,该光学参考腔由超低膨胀玻璃(ULE)制成。系统设计紧凑,支持将高真空,恒温,主动隔震和噪音隔离等各单元集成到一个标准19”机柜中,确保激光输出源的超窄线宽和超高稳定性。在ORS-Cubic 中,采用了与英国国 家物理实验室合作开发的腔长为5厘米的立方腔体。刚性的腔体支撑设计方便系统的长途运输,保证在系统运输至目的地时,无需重新调节激光与参考腔之间的耦合。每台光学参考系统在出厂前只有与另一套参考系统相互比对,或者通过三角帽比对法 (three cornered hat comparison)才能够通过各种苛刻性能测试,从而确保系统稳定优异的出厂指标。

Options

  • Doppler cancellation system

    Product Code: ORS-Doppler

    For long distance transmission of sub-Hz linewidth through optical fibers (over 5 or 10 m) we recommend active phase noise compensation of the ORS Output. This involves measuring the phase noise induced by temperature variations and vibrations in the fiber through a back-reflection, and actively compensates this with a phase-locked loop.

  • Active RAM cancellation

    Product Code: ORS-RAM

    The residual amplitude noise (RAM) can be actively cancelled with an additional phase-locked loop in the ORS.

  • Frequency shifting AOM

    Product Code: ORS-Frequency Shift

    The ORS can be tuned over tens of picometers in steps of the free-spectral-range. To reach a specific frequency in-between these steps (e.g. the Strontium transition at 698 nm), an additional noise-free frequency shift is required using acousto-optic modulators. ORS-Frequency Shift provides the precise output at the desired frequency for the ORS.

  • Frequency doubling

    Product Code: ORS-SHG

    It can be advantageous to lock the CW at half the frequency of the desired output, and add second harmonic generation (e.g. 1397 nm for the Strontium clock transition, with SHG to 698 nm). Frequency doubling can be integrated into your ORS system with free-space or fiber-coupled output.
