Class Description

class atomiq.components.laser.Laser(laser_source, zero_freq=None, *args, **kwargs)

Bases: LaserSource

Laser light that can be modulated

Since we inherit from LaserSource here, a Laser object can itself again be a LaserSource for another Laser object. This way one can describe consecutive manipulations from a LaserSource to the final Laser object.

Parameters:

• laser_source (LaserSource) -- The laser source that this laser is taken from

• zero_freq (TFloat) -- absolute frequency in Hz that should be considered zero. This allows to reference the laser frequency relative to e.g. an atomic transition. If not set, the detuning will be relative to the lock point of the laser source

set_frequency(frequency)

Set the absolute frequency of the light after modulation

Parameters:

frequency (artiq.compiler.types.TMono('float', OrderedDict())) -- Absolute frequency of the light after modulation in Hz

set_detuning(detuning)

Set the detuning of the light from the frequency defined by zero_freq

Note

If you are using a modulator (e.g. AOM) the center frequency is not taken into account. If you want to set the detuning from the center frequency of the modulator use self.modulator.set_detuning

Parameters:

detuning (artiq.compiler.types.TMono('float', OrderedDict())) -- Detuning in Hz

detune(frequency)

Alias for set_detuning()

Parameters:

frequency (artiq.compiler.types.TMono('float', OrderedDict()))
