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
