Tunable Laser C-band and L-band

Pure-Photonics ITLA Laser

This tunable laser in the C and L-band from Pure-Photonics can be controlled via serial communication.

Prerequisite

Please install the PySerial package by running the following command:

pip install pyserial

Example

import time
from itla import ITLA


def main():
    port = "COM3"  # Replace with the appropriate COM port for your ITLA laser
    itla_laser = ITLA(port)

    # Set laser power on
    itla_laser.set_laser_power_on()
    print("Laser power on")

    # Wait for 5 seconds
    time.sleep(10)

    # Get measured optical output power in dBm
    optical_output_power_dBm = itla_laser.get_measured_optical_output_power_dBm()
    print(f"Measured optical output power: {optical_output_power_dBm} dBm")

    # Set laser power off
    itla_laser.set_laser_power_off()
    print("Laser power off")

if __name__ == "__main__":
    main()

This example code does the following:

1. Imports the necessary modules and the ITLA class from the itla.py file provided.

2. Defines a main function that:

   • Assumes you have your Pure-Photonics ITLA laser connected to a serial port.
   • Sets the laser power on.
   • Waits for 10 seconds, and then gets the measured optical output power in dBm.
   • Sets the laser power off.

Make sure to replace the port variable with the appropriate COM port for your Pure-Photonics ITLA laser.
