Connecting to iBeam smart by Toptica in Python

Instrument Card

The iBeam smart is the ultimate choice when looking for a high-performance, ultra-reliable OEM single mode diode laser system. Record values at output power, combined with excellent power and beam pointing stability are setting the standard in the class of compact diode lasers. Its flexible, µ-processor based electronics will make system integration a snap. Features as FINE, SKILL and AUTOPULSE are capable to solve common problems of your application.

Connect to the iBeam smart in Python

Read our guide for turning Python scripts into Flojoy nodes.

Flojoy

PROTOCOLS > SCPI

📄 IDN

Query a device's identity through the universal *IDN? SCPI command.

📄 MEASURE VOLTAGE

Query an instrument's measured output voltage, such as a DMM or power supply.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

PyMeasure

Here is a Python script that uses Pymeasure to connect to an iBeam Smart laser:

from pymeasure.adapters import VISAAdapter
from pymeasure.instruments.toptica import IBeamSmart

# Create a VISA adapter and connect to the instrument
adapter = VISAAdapter("SomeResourceString")
laser = IBeamSmart(adapter)

# Set the output power of channel 2 to 1000 µW
laser.ch_2.power = 1000

# Enable channel 2
laser.ch_2.enabled = True

# Shutdown the laser
laser.shutdown()

Explanation:

1. Import the necessary modules from Pymeasure.
2. Create a VISAAdapter object by providing the resource string of the instrument.
3. Create an IBeamSmart object by passing the adapter to it.
4. Set the output power of channel 2 to 1000 µW by assigning the desired value to the power attribute of ch_2.
5. Enable channel 2 by assigning True to the enabled attribute of ch_2.
6. Shutdown the laser by calling the shutdown method of the laser object.
