How Can Pulsed Diode Laser Light Sources Enhance Your Imaging Applications?

Pulsed diode laser light sources are used in various imaging applications because of their capacity to greatly improve image quality. Across scientific and industrial research and development, pulsed diode lasers are used as a high-end light source for the visualization of the most challenging processes, such as additive manufacturing, flow and spray studies, or welding.  

A pulsed diode laser light source produces short pulses of light at high repetition rates. Troubleshooting of industrial processes, failure analysis, and material inspection are a few examples where high-speed imaging is used to visualize and analyze fast and complex phenomenon. In this blog post, we look at how pulsed diode laser light sources enhance your imaging applications.  

The Advantages of Pulsed Diode Laser Light Sources 

Several key characteristics of pulsed diode lasers contribute to their effectiveness and reliability in imaging applications. The advantages include high pulse power and brightness, possibility to use very short pulse durations and high repetition rates. Some additional benefits are mentioned below.

The compactness of pulsed diode lasers makes them suitable solutions for settings with limited space and enables them to be integrated into existing systems. Another benefit is that the light source can be positioned very close to the process, even in very confined spaces, by using a fiber optics.  

High-speed capabilities 

Pulsed diode lasers can operate at extremely high repetition rates, synchronously with high-speed cameras.  

In ultra-high-speed imaging applications, short camera exposure times inherently limit the amount of light collected by the camera, resulting in dark images. 

Pulsed diode lasers solve this problem very efficiently by illuminating the scene with a bright pulse during each camera frame. This technology enables excellent image quality for the visualization of even the fastest and most challenging processes.

Applications that typically benefit from the laser’s high speed include process development, quality control, flow visualization, ballistics, detonation, material mechanical testing.  

Precise pulse control 

Pulsed diode lasers can generate very short pulses of light with precise timing and duration. 

Short pulses are necessary to eliminate motion blur when imaging fast moving objects. Using short pulses also mitigates the risk of damaging samples.  


Pulsed diode lasers can be monochromatic, which means they emit laser light at one specific wavelength of the spectrum (example: 640nm, 810nm).  

Used in combination with the corresponding band-pass filter at the camera side, this setup provides excellent image quality, especially when visualizing bright processes such as welding or explosions.
