Class Description

class atomiq.components.lock.DetunableLock(settle_time=0, blind=False, *args, **kwargs)

Bases: Lock, Parametrizable

This is a very generic class to describe a laser lock where the lock offset can be changed. It is characterized by some means of a reference frequency and a detunable offset to that frequency at which the lock tries to stabilize.

Most likely you want to use a more specific class inherited from this one.

Parameters:

• settle_time (TFloat) -- Time in s the lock needs to settle after a detuning of the lock point

• blind (TBool)

A Parametrizable is an entity that can be controlled by one or more continuous parameter(s)

set_frequency(frequency)

Set the absolute frequency of the locked line

Parameters:

frequency (artiq.compiler.types.TMono('float', OrderedDict())) -- The absoulte frequency at which the system should lock

set_detuning(offset_frequency)

Set the frequency relative to the reference frequency, i.e. set the lock offset.

Parameters:

offset_frequency (artiq.compiler.types.TMono('float', OrderedDict())) -- new lock offset in Hz
