Options

• Optics Module for Input Coupling, PDH Locking, and Monitoring

  Product Code: ORC-OPTIC-CUB / ORC-OPTIC-CYL

  Two modules holding all optics required for input coupling one single wavelength to the cavity in the range from 633 to 1560 nm, Pound-Drever-Hall locking as well as power monitoring of the transmitted light. The modules are rigidly mounted onto the cavity housing making realignments after transportation obsolete.

• Optics Module for Input Coupling, PDH Locking, and Monitoring

  Product Code: ORC-OPTIC-DUAL

  Complementary optics mounted on the ORC-OPTIC-CUB/ORC-OPTIC-CYL module for coupling a second laser wavelength in the range from 633 to 1560 nm simultaneously to the same cavity. This add-on requires the ORC-OPTIC-CUB/ORC-OPTIC-CYL option.

• ORC Mirror Coatings for Multiple Wavelengths Package

  Product Code: ORC-MWL

  For the simultaneous stabilization of multiple lasers to the same reference cavity, custom coating designs and cavity mirrors which are highly reflective at two or multiple wavelengths can be tailored to your application.

• 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.

• Pound-Drever-Hall Servo Electronics Package with TEC controller and 1542 / 1550 nm Laser Module

  Product Code: ORC-SYNCRO-RLD

  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, a TEC controller for temperature stabilization and a laser module at 1542 or 1550 nm.

• Characterization of the Zero-Crossing Temperature

  Product Code: ORC-CTE

  Determining precisely (within 50 mK) the zero-crossing temperature of the coefficient of thermal expansion (CTE) of the ULE reference cavity is fundamentally important for stable operation. This procedure requires a dedicated measurement infrastructure and is very time consuming due to the long thermalization time constant. Menlo routinely characterizes the CTE zero-crossing temperature, allowing you to dedicate more time to your application.
