Description

The ORC-Micro is the optical reference cavity (ORC) with the most compact form factor, for all applications that require short-term (10 ms) laser stabilization and sub-kHz stability performance.

The cavity provides price-sensitive single-color (1542/1550 nm) optical reference options, both in free-space and fiber coupled configurations, with a free-spectral range (FSR) of 4 GHz and a finesse of >50k. Moreover, temperature tuning and stabilization is achieved via a Peltier element. The ORC-Micro is designed to be the stable reference for applications such as laser cooling and thermal beam experiments, complementing the ultimate finesse performance of the ORC-Cubic and Cylindric.

In the standard free-space solution, an external laser can be coupled to the ORC-Micro through a viewport, while monitoring the transmission output signal. Several options including fiber-coupling and Pound-Drever-Hall (PDH) electronics are available for customization. In particular, with the fiber in- and outcoupling setup the user can benefit from a plug-and-play solution for telecom laser-stabilization applications.

Finally, the considerably reduced form factor of the ORC-Micro enables OEM integration, in synergy with other Menlo Systems’ products.

Options

  • ORC-Micro Fiber In- and Outcoupling Option

    Product Code: ORC-Micro-FC

    ORC-Micro fiber ports for laser input and transmission output monitoring.

  • ORC-Micro Stability Characterization

    Product Code: ORC-Micro-MADEV

    Modified Allan deviation (MADEV) measurement to verify the ultimate achievable stability and drift performance. All components from one supplier with full automation guarantees hands off operation and more time for your experiments.

  • TEC Driver Package

    Product Code: ORC-TEC

    A TEC driver to stabilize the temperature of the reference cavity to the zero-crossing temperature of the coefficient of thermal expansion.

  • PDH Optics

    Product Code: ORC-PDH-Optics

    Fiber-coupled compact optical unit for the generation of the PDH reflection signal.

  • Pound-Drever-Hall Servo Electronics Package with TEC controller

    Product Code: ORC-SYNCRO

    For stabilizing the laser to the cavity, this package provides all required electronics in a single configurable device, i.e., Menlo’s SYNCRO controller (3rd generation). The SYNCRO provides full software control of all parameters and intuitive use via touchscreen. This 3U, 19-inch device can also be remotely accessed via LAN. The package includes phase modulation and demodulation, and a fast analog PI²D controller (>10 MHz bandwidth) providing two servo outputs for fast and slow actuators and a TEC controller for temperature stabilization.
