Large high-power laser windows

Optical Surfaces Ltd, specialists in large high precision optics, have considerable expertise in the supply of high-power laser windows up to 600mm in diameter. Working with a range of glasses including BK-7 and fused silica, that offer good homogeneity and transmission from the UV to the Near-IR, Optical Surfaces Ltd. is today one of the world's leading suppliers of large windows for high-power Nd:YAG lasers.

Benefiting from a stable manufacturing environment and proprietary production techniques Optical Surfaces Ltd.'s skilled and experienced craftsmen are able to routinely produce large high-power laser windows with typical wavefront error of lambda/10 and surface finish of 40/20 -10/5.

To optimise the performance of rapid-pulsed (femtosecond) high-power lasers the company 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 Ltd 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 (e.g. 372mm diameter and 10mm thickness).

Optical Surfaces ISO 9001-2000 approved manufacturing facility provides the flexible resources to supply from single specialist requirements to OEM quantities. All high-power laser windows are provided with a complete quality test assurance report.
