Most controllers are a combination of these three elements. However, there are several ways how to combine and physically implement these elements. Consequently, there is a large variety of
The DLC pro lock is a digital lock based on a field-programmable gate array (FPGA) and reaches bandwidths of up to 30 kHz. It excels in terms of convenience and ease of use as it provides remote
The last element of every feedback loop for phase and frequency locking is the actuator. It performs phase and frequency adjustments based on the control signal. While external components like
Changing the temperature of the diode will change the laser frequency by a large amount, typical tuning coefficients are changes of 0.1 nm/K. However, as it typically takes quite a while for the
TOPTICA Solution
TOPTICA´s CoSy includes a complete optical setup for Doppler-free saturation spectroscopy together with a controller which performs the subtraction of the reference signal from the
TOPTICA Solution
Both options of generating the error signal from the spectroscopy signal are supported by TOPTICA´s DLC pro Lock, which is a software option of TOPTICA´s laser controller DLC pro

Phase and Frequency of Laser Light
Laser light can be described by its space and time-dependent electric field E(x,t). For the purpose of discussing phase and frequency locking of lasers, the
