MKS Instruments, Inc., a global provider of enabling technologies that transform our world, has announced the Ophir® 70K-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 70K-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 70K-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.
The 70K-W Ultra-High Power Sensor is designed for flexibility, able to support the use of tap water or deionized (DI) water for cooling. It is also able to accommodate vertical and horizontal beams. The measurement unit is equipped with Ethernet and RS232 interfaces enabling seamless integration into application setups. The sensor can be powered using a local power supply or via the Ethernet communication port using Power Over Ethernet (POE).
