Precision Windows for High Power Laser Experiments by Optical Surfaces Ltd.

March 18, 2019

Benefiting from an ultra-stable production environment and proprietary polishing techniques – Optical Surfaces Ltd. is able to routinely produce high-power laser windows up to 600mm in diameter with typical wavefront error of lambda/10 and surface finish of 40/20 to 10/5.

Working with a range of optical materials including BK-7 and fused silica, which offer good homogeneity and transmission from the UV to the Near-IR, Optical Surfaces is today a preferred supplier of large, precision windows to many high-power laser research groups around the world.

To optimise the performance of rapid-pulsed (femtosecond) high-power lasers – Optical Surfaces Ltd is able to supply the latest dielectric coatings on windows to provide minimum pulse distortion, maximum usable bandwidth and durability.

In applications where there is significant risk of mobile material as a result of high-power laser ablation – Optical Surfaces also has considerable experience of producing large ultra-flexible windows (debris shields) to protect the final high precision lens that focuses laser energy onto the targets.  Manufacturing debris shields combines the dual demands of producing a precision wavefront (typically lambda/5 to lambda/10) on a flexible window with a high diameter to thickness ratio.

Optical Surfaces Ltd has been producing optical components and systems for more than 50 years and is now accepted as one of the world’s leading manufacturers of high-precision optics for aerospace and space research. The company’s ISO 9001-2015 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in solid chalk where temperature remains constant and vibration is practically non-existent. With such stable conditions testing, particularly with long path lengths, becomes quantifiable and reliable. Working with these natural advantages is a highly skilled team of craftsmen with a commitment to excellence in both product quality and customer service.
