Phase-locked loop frequency multiplier and divider use cases
Introduction The digital phase-locked loop (PLL) is a powerful technique used in Moku devices to continuously track the phase of an input signal with zero dead time. This technique is used in Moku’s Lock-in Amplifier and Laser Lock Box to generate a phase-locked demodulation signal, and in the Phasemeter to measure the real-time phase, frequency,…

Phase Detection with Lock-in Amplifier and Phasemeter
Precise and sensitive phase detections are often required for impedance and optics-based measurements. For example, measuring the phase shift between current and voltage reveals the complex impedance of a device or component. Very small displacements can be measured by the phase shift between control and measurement arms from an optical interferometer. Liquid Instruments’ Moku platform…

Stabilizing Multiple Lasers Simultaneously with Moku:Pro
Achieving phase coherence across multiple lasers can be challenging and expensive. Moku:Pro’s Phasemeter exceeds the performance of conventional lock-in amplifiers and makes it easier to stabilize, steer, and measure multiple lasers in real-time with unmatched precision. With exceptional dynamic range, zero dead-time, and measurement precision, the Phasemeter can handle your most challenging phase measurement needs.…

Laser Frequency Offset Locking
Stability is vital for sensitive measurement systems. It is the key parameter that determines the precision and accuracy of such systems. Like a voltage reference in a voltmeter, the frequency and phase of a laser must be referenced to a stable source. In this technical note, we look at offset phase locking in optical systems…
