Description

附带真空腔的高精细度Fabry-Pérot腔体非常适用于超稳激光系统。谐振腔体由超低膨胀(ULE)玻璃制成。腔镜基片可以选配ULE或熔融石英(FS),腔镜镀膜可选配标准离子束溅射(IBS)或低热噪声单晶镀膜(XTAL)。Menlo Systems是基于索雷博的晶体镀膜解决方案技术的高精细度光学参考腔的独家经销商。紧凑的真空腔设计在保证了超窄线宽和超高稳定性同时,最大程度地减少了实验装置对空间的需求。ORS-Cubic-Cavity基于被牢固支撑的5 cm长立方体腔(3 GHz 的自由光谱程,NPL专利技术),刚性的构架结构支持腔体的长途运输,而无需重新校准。ORS则基于PTB设计的长度为12.1厘米的圆柱体腔体(1.24 GHz 的自由光谱程)。同样,其配备的机械锁定装置支持系统在交付后能够实现快速本地安装,而无需重新校准。通过真空通孔可以很容易对内置的热敏电阻和珀尔帖元件进行操作。

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.

  • 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.
