Beam Sampling with Diffractive Optics

08 Jan 2018

For high power laser applications in materials processing it can be important to monitor

both laser power levels and beam profi le in order to ensure a consistent quality product.

By implementing real-time monitoring a user can make changes to minimise optical losses

and wavefront distortions.

Using a diffractive beam sampler from Holo/OR allows for most of the light to continue forward

‘unaffected’ in the zero order, while a small amount of the beam’s energy is diffracted

into a higher order. From a collimated input beam, the output beams exit from the diffractive

optical element with an intensity (relative to the incident beam) and a separation angle

determined during the design of the element based on a customer’s system requirements.

The two sample beams, located to the left and right of the main beam (+1 and -1 orders) are

an exact replica of the main beam’s profi le, making it perfect for real time beam profiling

applications.
