SLICE-DHV Performance
The SLICE-DHV dual-channel high-voltage amplifier is a powerful tool for driving PZTs and other capacitive loads in the lab. However, it is important to understand the capabilities and intended use cases of the SLICE-DHV before employing it in your system.
Specifically, some care must be given to ensuring that the SLICE-DHV can drive its load at the desired bandwidth. This application note will discuss choosing an appropriate load for the SLICE-DHV given some bandwidth constraints, as well as how to pick the correct Modulation and Output settings to fit your system.
Application Note: Simplified offset stabilization of a low-noise 1 GHz oscillator
Summary: We utilize the Octave Photonics Comb-Offset-Stabilization Module (COSMO) to detect the carrier-envelope-offset frequency (fCEO) of a Menhir Photonics 1-GHz, 1550-nm oscillator with less than 140 pJ of pulse energy (<140 mW average power). A Vescent Photonics SLICE-OPL offset-phase-lock controller provides the feedback signal to the oscillator and establishes a tight lock with only 0.26 radians of residual phase noise. Together, this demonstrates a simple method for building compact and reliable frequency comb sources at GHz repetition rates.
Introduction: Laser frequency combs are essential optical-to-microwave converters for applications such as optical atomic clocks and high-resolution dual-comb spectroscopy. Frequency combs are based on femtosecond mode-locked lasers that have their repetition rate (frep) and carrier-envelope-offset frequency (fCEO) stabilized. The repetition rate can easily be stabilized by detecting the pulse train with a photodetector and providing feedback to the laser oscillator. Detecting fCEO is more difficult and is typically accomplished through f-2f self-referencing, where the spectrum is broadened to at least one octave via supercontinuum generation. The low frequency side of the spectrum is then frequency doubled in a second-harmonic-generation material and overlapped in time with the high-frequency spectrum on a photodetector, detecting the microwave fCEO.
