Lasermet have announced the launch of their new ADM-1000 advanced laser power meter which offers market-leading rise time, excellent power-measuring performance combined with the ease of using a ...

As lasers become more powerful and diverse, so power meters have had to adapt. Ephraim Greenfield of Ophir Optronics gives us an overview of the different power meters available and outlines how they ...

Fig 1. The MEMS pressure sensor detects the tensile stress on a thin silicon membrane that changes the piezo-resistance of elements on the membrane’s surface. Fig 2. The MEMS sensor’s piezo-resistive ...

NIST researchers have developed a compact, high-accuracy, point-of-use high-power laser power meter in the form of a folding mirror called “Smart Mirror,” making in-situ, real-time measurement of ...

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.

In Case Study: Medical Laser System; Part 1: Stabilizing a Laser Feedback Control Loop, the nonlinear flashlamp in the laser control loop had a parabolic transfer function which was gain-compensated ...
