Moku:Lab’s Laser Lock Box enables you to lock a laser’s frequency to a reference cavity or atomic transition using high‑performance modulation locking techniques. The Laser Lock Box includes a ‘Tap‑to‑Lock’ feature, enabling you to quickly lock to any zero-crossing on the demodulated error signal. It also features an integrated 2‑channel oscilloscope, allowing you to observe signals at any point in the signal processing chain at up to 500 MSa/s.

  • Stabilize a laser’s frequency to a reference cavity or atomic transition : Supported locking techniques include Pound-Drever-Hall (PDH) locking, Heterodyne offset phase-locking, RF locking, and Dither locking.
  • Block diagram view of the signal processing chain : Clear overview of the laser locking to aid control and understanding.
  • Flexible configuration of the demodulation source : Demodulate signals with internal or external local oscillators.
  • Scan for resonances : Positive sawtooth, negative sawtooth or triangle waveforms.
  • Tap-to-Lock : Quickly lock to any zero-crossing in the error signal using the ‘Tap-to-Lock’ feature.
  • Integrated oscilloscope : Place virtual probes within signal processing chain to observe signals using an integrated oscilloscope.
  • Post-demodulation filtering : Filter demodulated signals with up to fourth order infinite impulse response low-pass filters: Butterworth, Chebyshev, Inverse Chebyshev, Elliptic, Gaussian, Bessel, Legendre.
  • Maintain frequency lock with two independent PID controllers : Individually configure high- and low-bandwidth PID controllers for fast and slow feedback.
  • Custom controls : Quickly access the controls you need with a customizable control palette view.
  • Local oscillator frequency : 1 mHz to 200 MHz (3.55 µHz resolution)
  • Scan waveforms : positive sawtooth, negative sawtooth, triangle
  • Scan frequency : 1 mHz to 1 MHz
  • Low-pass filter corner frequency : 1 kHz to 14 MHz
  • Filter roll-off : 6 dB / 12 dB per octave filter roll-off
  • Low-pass filter types : Butterworth, Chebyshev, Inverse Chebyshev, Elliptic, Gaussian, Bessel, Legendre
  • Coupling : AC/DC
  • Input impedance : 50 Ω / 1 MΩ
