Overview

The SMC-Series modules are the ideal instruments for controlling the current and the temperature of narrow linewidth laser diodes. With an ultra-low noise current sink (SMC11) and sub-mK thermal control stability (SMC20 & SMC31), the SMC-Series is the right choice for the most demanding applications. Because SMC-Series was first designed for frequency stabilization and OPLL applications, the SMC11 current sink provides in addition two current modulation inputs since ultra-low noise current and fast current modulation are key parameters for achieving the best phase noise performance of your stabilized lasers. Using the SMC-Series laser diode controller with the SMA– or SMB-Series modules, complete turn-key solutions are available for your laser frequency stabilizations or phase-locked lasers.

Applications

Overview

The SR100 Estélas is a low-noise power supply providing ±15V and +5V and optionally +24V. The SR100 was first designed to provide a quiet environment to operate our ultra-low noise laser current source (SMC-Series). For this purpose, three SPS20 Cagire modules are assembled in a 3U desktop case to power up to 2 complete laser diode controllers and their dedicated laser frequency control electronics (SMA– and SMB-Series). Because they have little to no ability to reject supply variations, many RF subsystems should also benefit from the low-noise features of the SR100 Estélas to prevent unwanted side bands and low signal-to-noise ratio.

Overview

The SPS20 Cagire is a low-noise power supply based on a linear AC/DC converter. It was first designed to provide a quiet environment to operate our ultra-low noise laser current source (SMC-Series).

SMA11 – DC Error Controller

Features

  • Front panel knob (+/-500mV or +/-5V)
  • BNC control input (+/-10V)
  • DC-Error signal monitoring
  • For use with SMA10 RF Mixer module
  • EMI noise immunity
  • Free of digital noise
  • Schematic diagrams included

Contact Sisyph

Applications

  • Locking point control
  • RF-optical heterodyne lock
  • Laser frequency stabilization
  • Pound-Drever-Hall lock
  • Residual amplitude modulation (RAM) compensation
  • Ideal for rapid prototyping

Overview

The SMA11 DC Error Controller module was designed to control the locking point of a RF-optical heterodyne lock (also known as Pound-Drever-Hall lock).

In a well-designed laser frequency locking electronics, the DC offset of the error signal can be neglected and no lock-acquistion  problems should occur. But electronics are not the only source of offset voltages and, faced with a high-level of residual amplitude modulation (RAM) the resulting DC baseline can be large enough to induce significant locking point errors. Moreover, in presence of high-finesse cavities, this DC component due to the RAM makes the lock acquisition difficult, indeed impossible.  In such a case, a RAM offset cancellation must be provided.

For this purpose the SMA11 module is used to control the DC level of the error signal delivered by the SMA10 RF Frequency Mixer.  The DC level is either adjusted using the front panel knob or the input voltage. The DC range of the potentiometer (+/-5V or +/-500mV) is selected using the dedicated switch. The control voltage resulting from the combination of these settings can be summed to the mixer output through the analog bus connector. This signal is also copied and fed to the front panel for monitoring.

Like all SM-Series modules, the SMA11 is shipped with the schematic diagrams of its electronic circuitry providing all required information for advanced users.
