Features

Ultra-high-power average power measurement from short exposure:

The 70K-W has unique features allowing average power measurement of ultra-high-power lasers from a very short exposure up to 100 kW. The typical response time of calorimetric sensors is in the range of tens of seconds. There are laser-based systems commonly found in directed energy applications (but not only), which can emit the beam for only a few seconds (due to power and other constraints). In such cases, a regular power sensor will be used as a beam dump, and a cumbersome setup will be needed to measure the average power indirectly. The 70K-W's unique capability to obtain the average power from an energy measurement of a laser “pulse” with a duration of few seconds, simplifies the measurement setup and allows direct measurement of the laser power while dumping the excess power, making the process simpler, cost effective, and safer, especially when dealing with ultra-high power.

Support horizontal and vertical measurement orientation:

Different applications and use cases require different beam orientations. For testing and development purposes, directed energy systems usually use a horizontal beam. However, in industrial settings, vertical beams are often preferred due to process requirements and safety considerations. The system is designed to perform measurements both horizontally and vertically, offering the flexibility needed to accommodate varying operational and safety needs.

Operational safety:

The system guarantees operational safety with an extremely low back reflection of <0.5% and a built-in interlock output, offering several configurable trigger criteria. Together, these features are essential for ensuring safety in high-power environments.

Real time laser power monitoring​:

There are cases, users may want to check the stability of their laser or use an indication on laser power as an input to one of their systems. By using the integrated photodiode output of the 70K-W, it is possible to accommodate these needs, enabling direct connection to third-party devices for monitoring laser stability or providing instantaneous control and feedback.

Easy integration with 3rd part systems​:

The 70K-W can be part of a larger system and requires integration. This can be achieved using Ethernet, RS232 communication interfaces, or an analog output. The sensor can operate with regular tap water​ or deionized water to accommodate different cooling systems.
