Ophir Photonics Launches 100K-W Laser Power Meter

North Logan, Utah - Ophir Photonics, global leader in precision laser measurement equipment and a Newport Corporation brand, today announced the 100K-W Laser Power Meter, the newest addition to the company's line of very high power laser sensors.

The first commercial sensor for measuring very high power 100kW lasers, the 100K-W meter is designed for fiber lasers used in industrial material processing, such as thermal ablation, heavy-section welding, and metal forming, as well as military directed-energy applications.

The portable meter features a unique design that allows measurement of very high power, near infrared, Nd:YAG and fiber lasers. NADEX Laser R&D Center recently successfully tested the 100K-W at up to 100,000 Watts on a fiber laser mounted on a robot arm.

"Measurement and control of a laser's power is the only way to achieve reproducible results, especially for those operating at very high powers," said Ephraim Greenfield, CTO, Ophir Photonics. "The 100K-W power meter measures laser power at an unprecedented four (4) times the power of any other commercial laser meter, including Ophir's own 30K-W Laser Power Meter. It is designed to measure very high power lasers to ensure precision in cutting and directed energy applications."

The 100K-W Laser Power Meter measures high power beams at a distance past the focal spot of the laser or, alternatively, at a distance from the diverging fiber output where the beam has expanded to about 100mm diameter.

A reflective cone in the meter deflects the laser beam onto the inner circumference of the sensor. This increases the radiated area and reduces the power density to manageable levels. As the cone dissipates the beam, it captures over 99% of the radiation, minimizing safety hazards. The response time of the 100K-W is less than 1 minute, a fraction of the time required by custom, non-commercial systems.

Unlike other high power measurement systems, the 100K-W Laser Power Meter is a compact, portable unit. It consists of a beam dump with overall dimensions of about 50cm diameter x 50cm deep, and a water flow power measurement unit of 11x15x34cm. The meter connects to a PC via RS-232 and is provided with software that displays and graphs the power and water flow rate. A smart connector output displays power readings on any of Ophir's smart displays.
