Laser Beam Profiling with the Acuros® CQD® SWIR Sensors

Lasers are used in an endless number of industrial applications. Whether you use a laser to take precise measurements, conduct surveys, do telecommunications work, or even use it in the medical field for something like laser eye surgery, you need to understand all of the characteristics and quality of your laser.

Laser Behavior

You can generally predict how a laser will behave based on how it is produced and how other models have performed in the past – but certain extraneous factors require verification and measurement. Things like manufacturing tolerances for lenses and mirrors and something as minor as the ambient conditions around your laser cavity can all have a sizeable effect on how well your laser functions compared to what you may have been expecting.

Given the different types of laser beams, spatial distributions, and their evolution as they propagate in free space and through optical elements, measurement of the beam profile is critical to quantify the irradiance at the point of the application. Monitoring the beam profile can also identify laser beam anomalies.

Cameras use a two-dimensional array of square or rectangular pixels as the imaging device. The intensity distribution of a laser or light source is recorded pixel by pixel and displayed as either a topographic or three-dimensional contour plot. The chief advantage of such profilers is that they can detect and display any structure that may exist on the profile and can be used with both continuous wave (CW) and pulsed lasers.

What is laser beam profiling looking to measure?
– Beam width
– Beam shape
– Energy uniformity
– Beam quality

You can visualize your beam like never before with the Acuros® 1920L SWIR Camera. The significant advantage that a camera has over other methods of beam profiling like pinhole profilers and slit profilers is that you get real-time measurements and views of your laser in action. SWIR sensors are specially designed to reduce all laser-induced fringing effects.

Laser Beam Inspection

Laser beam profiling, free-space optical alignment, fiber optic alignment systems, scientific research and medical optics systems all use integrated SWIR cameras. These key instrumentation applications, and others require sensors with high pixel density, and large format arrays, all delivered at the lowest cost per megapixel.

The family of Acuros CQD SWIR and e-SWIR cameras meet the challenges of the optics and optical systems market. Review the specifications of our key platform cameras, and contact SWIR Vision to discuss your imaging needs.
