MKS Instruments, Inc., a global provider of enabling technologies that transform our world, has announced the Ophir® 70 K-W Ultra-High Power Laser Sensor, an efficient solution for measuring ultra-high power levels up to 70 kW with high accuracy and dependable performance, at SPIE's Photonics West 2025. This water-cooled, calorimetric sensor measures powers from 2 kW to 70 kW across the spectral range of 900 - 1100 nm and 10.6 µm. The lightweight design and multiple interfaces - including Ethernet and RS232 - for communication, analog output, and real-time laser power monitoring output, allow easy integration into various industrial and defense applications, such as high-power fiber laser development and testing, industrial cutting, and directed energy systems. Enhanced safety is achieved through a built-in interlock output and exceptionally low back reflection of <0.5%, a critical feature for high-power environments.

"The drive for high power lasers keeps us pushing the forefront of innovation," said Reuven Silverman, General Manager, Ophir Photonics Products. "The Ophir 70 K-W Ultra-High Power Laser Sensor is an adaptable, reliable, and efficient sensor that delivers accurate and reliable high power measurements while providing a cost effective option for ultra-high powers of 2 kW to 70 kW."
The Ophir 70 K-W Ultra-High Power Sensor is a lightweight design, weighing under 40 kg without water. The sensor features a large 130 mm aperture and is compatible with a wide NA range from collimated beams up to 0.22. The sensor also supports customer-provided fiber adapters for tailored applications. An integrated photodiode provides real-time laser power monitoring, which can be directly connected to third-party devices for instantaneous control or feedback.
