QCoDeS Example with Gentec Maestro¶

[1]:

from qcodes_contrib_drivers.drivers.Gentec.Gentec_Maestro import Gentec_Maestro

Initialize the instrument using its ASRL address¶

[2]:

gentec = Gentec_Maestro(name="Gentec", address='ASRL16::INSTR')

Connected to: Gentec Maestro (serial:None, firmware:1.04.16) in 0.09s

First, we read the currently set wavelength.

[3]:

print(gentec.wavelength.label, ': ', gentec.wavelength.get(), gentec.wavelength.unit)

Wavelength :  1024 nm

Now let’s set the wavelength of our laser source and confirm that it was set.

[4]:

gentec.wavelength.set(660)

[5]:

print(gentec.wavelength.label, ': ', gentec.wavelength.get(), gentec.wavelength.unit)

Wavelength :  660 nm

Let’s read the laser power detected by the Gentec.

[6]:

print(gentec.power.label, ': ', gentec.power.get(), gentec.power.unit)

Power :  0.634878 W

We can also set an offset in order to remove any background from the measurement.

[7]:

print(gentec.zero_offset_enabled.label, ': ', gentec.zero_offset_enabled.get(), gentec.zero_offset_enabled.unit)

Zero offset enabled :  0

[8]:

gentec.set_zero_offset()

[9]:

print(gentec.zero_offset_enabled.label, ': ', gentec.zero_offset_enabled.get(), gentec.zero_offset_enabled.unit)

Zero offset enabled :  1

Let’s now repeat the power measurement.

[10]:

print(gentec.power.label, ': ', gentec.power.get(), gentec.power.unit)

Power :  -0.000390634 W

Finally let’s clear the offset.

[11]:

gentec.clear_zero_offset()

[12]:

gentec.close()
