Measuring Challenges Of Wide Divergent Beams
To guarantee the high quality of VCSELs, LEDs, edge emitting, and fiber laser devices, it is essential to analyze the beam profile. However, wide, divergent beams place specific requirements on the measurement system. The apertures of conventional beam profilers are too small to collect the entire spot of large or divergent light sources, while diverging beams cannot be accurately measured with regular detectors. These challenges have now been...  Continue Reading..

Characterizing A Laser Used In Metal Additive Manufacturing Equipment
In this application note, a developer of power-bed additive manufacturing systems needed a beam profiling system that could be used by their field technicians for setup and maintenance of customers’ lasers. The bulky water-cooled system they had been using was costly, and long lead times for sale and repair were unreasonable. Moving to a BeamGage® based system made setup quick and finding the focal spot location easy.  Continue Reading..

  • New F-Theta Lens For Ultrashort Pulse Electronics Production

    The new F-Theta lens for 532-nanometer applications is the second high-power lens for use in the green wavelength range in Jenoptik’s Silverline lens portfolio. The solid fused silica lens is especially designed for high-volume electronic production with ultrashort pulse lasers such as PCB depaneling.

  • Bright And Eye-Safe Machine Vision Laser

    The FLEXPOINT MVpulse laser module delivers an output power of up to 100 mW and fulfills all the requirements of laser classes 1 or 2. This is achieved with an integrated microcontroller that provides a continuous wave laser in such a way that individual pulses can be generated. MV output power is five times higher than in cw operation, with the laser class specifications maintained for the entire pulse sequence.

  • Laser Technology: New Trick For Infrared Laser Pulses

    Ordinary solid-state lasers, as used in laser pointers, generate light in the visible range. For many applications, however, such as the detection of molecules, radiation in the mid-infrared range is needed. Such infrared lasers are much more difficult to manufacture, especially if the laser radiation is required in the form of extremely short, intense pulses.
