The value to change the wavelength.

async clear_fault()

Clear the fault state of the laser.

async configure(config)

Configure the laser.

async connect()

Connect to the laser.

async disconnect()

Disconnect from the laser.

async read_all_registers()

async set_burst_count(count)

async start_propagating(data)

Start propagating the beam of the laser.

async stop_propagating()

Stop propagating the beam of the laser

async trigger_burst()

Trigger a burst.

Raises:

ValueError

Raised when mode parameter is not in list of accepted values.
