coherent_lasers

This repository contains python driver packages for various lasers manufactured by coherent. To facilitate communication with the devices, the drivers utilize:

1. low level SDKs provided by coherent
2. Serial communication via RS232 and equivalent protocols

Supported Lasers

1. Genesis MX

Repository is organized by laser model. Each laser model has its own directory containing the driver code.

Installation

You can install the coherent_lasers package directly from a GitHub release using pip.

coherent_version=0.1.0
pip install https://github.com/AllenNeuralDynamics/coherent_lasers/releases/download/v${coherent_version}/coherent_lasers-${coherent_version}-py3-none-any.whl

Genesis MX Laser Series Driver

A minimal python driver for a Genesis MX laser

Provides two classes for controlling a Coherent Genesis MX laser.

1. The GenesisMX class provides a comprehensive API for controlling the laser.
2. The GenesisMXVoxelLaser class provides a simplified API for controlling the laser based on the requirements of the Voxel library.

Supports connection via USB using the HOPS SDK provided by Coherent.

Usage

Lasers such as the Genesis MX series require that the HOPS dll files are installed and configured properly. (HOPS dependent lasers only work on Windows.)

Installing this package from the .whl file will include the necessary dependencies. Otherwise you will need to download the dll files and add them to your system path.

Once installed, you can test the driver using the following commands

For a simple command line interface to send commands to a hops device, you can run the following command:

cohrhops

Alternatively, run the following command to interact with connected Genesis MX lasers:
