nkt-basik 0.4.0

Python interface for the NKT Photonics Basik fiber seed laser

NKT-basik

Python interface for NKT Photonics Basik fiber seed lasers.

Install

pip install nkt_basik

API design

The package now exposes one high-level API layer:

• Basik
• LaserMode
• ModulationRange
• ModulationSource
• ModulationCoupling
• ModulationWaveform
• DeviceRef
• find_devices() / find_device() / find_devices_by_names()

Mode and modulation setters require enum inputs.

Quickstart

from nkt_basik import (
	Basik,
	LaserMode,
	ModulationCoupling,
	ModulationRange,
	ModulationSource,
	ModulationWaveform,
)

device = Basik("COM4", 1)

print(f"Name: {device.name}")
print(f"Wavelength: {device.wavelength:.4f} nm")
print(f"Frequency: {device.frequency:.4f} GHz")

device.mode = LaserMode.POWER
device.emission = True

device.modulation = True
device.modulation_source = ModulationSource.BOTH
device.modulation_range = ModulationRange.NARROW
device.modulation_coupling = ModulationCoupling.DC
device.modulation_waveform = ModulationWaveform.SINE
device.modulation_frequency = 100.0

device.frequency_setpoint = 275.1000

print(device.status)
print(device.error)

device.close()

Context manager usage is optional:

with Basik("COM4", 1) as device:
	print(device.name)

Discovery

from nkt_basik import find_device, find_devices, find_devices_by_names

all_devices = find_devices()
named = find_device("seed-a")
grouped = find_devices_by_names(["seed-a", "seed-b"])

find_devices() always returns a list (possibly empty).

Errors

• Connection failures raise nkt_basik.module.BasikConnectionError.
• Bad API value types raise nkt_basik.module.BasikTypeError.
• Register communication errors raise NKTRegisterException.
