Phase Lock to an Optical Reference  
URL: /application-notes/phase-and-frequency-locking-of-diode-lasers/error-signal-generation/phase-lock-to-an-optical-reference#c16011
An offset phase lock to a second cw laser can easily be implemented using TOPTICA´s FALC pro which will be presented in more detail in the application note “PID Feedback Controllers”. For…  
Phase Lock to an Optical Reference  
URL: /application-notes/phase-and-frequency-locking-of-diode-lasers/error-signal-generation/phase-lock-to-an-optical-reference#c15595
There are various ways to lock a laser to another optical reference. Here, the general principle of a phase lock to an optical reference will be described. The optical reference can e.g. be a second…

General Error-Signal-Generation Schemes - b) FM spectroscopy and top-of-fringe locking  
URL: /application-notes/phase-and-frequency-locking-of-diode-lasers/error-signal-generation/general-error-signal-generation-schemes#c15568
b) FM spectroscopy and top-of-fringe locking An alternative method is based on the principle of frequency modulation (FM) spectroscopy. The laser frequency is modulated, e.g. by modulating the laser…  
Error-Signal Generation  
URL: /application-notes/phase-and-frequency-locking-of-diode-lasers/error-signal-generation#c15562
Quite generally, generating an error signal consists of two steps. The first step is to create an optical signal using an optical setup involving a reference, e.g. one of those presented in the…  
Error-Signal Generation  
URL: /application-notes/phase-and-frequency-locking-of-diode-lasers/error-signal-generation#c15816
The goal of error signal generation is to create an electronic signal that is proportional to the laser´s deviation from a certain set frequency or phase which will be called lock point in the…  
Error-Signal Generation  
URL: /application-notes/phase-and-frequency-locking-of-diode-lasers/error-signal-generation#c16010
This application note deals with the question of how to generate an error signal for phase and frequency stabilization of lasers. First, general schemes which are independent of the choice of…
