Martin Wittmann, Senior Director Product Marketing for Visualization & Sensing at ams OSRAM, said: ‘By choosing the latest versions of the popular PLT family of laser diodes, customers benefit from excellent beam quality and tight tolerances, making it easier for them to produce better laser module devices.’ The new ams OSRAM chip improvement in beam quality means that laser-module manufacturers gain coupling efficiency when light is coupled into a waveguide or glass fiber giving greater flexibility in the specification of the required output power from the laser source. In addition, the new PLT3 and PLT5 lasers have a more homogeneous beam. This improves a laser module’s ability to illuminate a surface or object uniformly. Tighter tolerances reduce maximum power requirement ams OSRAM has enhanced its laser diode fabrication technology to narrow the distribution of values for key operating parameters across the population of production units. This makes it easier for laser module manufacturers to maintain the required tolerance in the driver circuits. In addition, the new lasers feature lower maximum values for operating current and voltage, as well as for threshold current. For instance, the maximum threshold current for the 30 mW green laser, the PLT5 518FB_P, has been reduced by around 25 percent from 60 mA in the previous generation of PLT5 products to 45 mA in the latest version. The tighter tolerances in the new diodes, and their lower operating current, mean that the power supply to the laser can be shrunk. The space and power savings enabled by use of the new PLT laser diodes is an important benefit for portable battery-powered devices in particular. Scanning applications enhanced by use of high performance green lasers A typical application that will benefit from the new ams OSRAM chip is barcode scanning with green lasers. Large warehouses or open-air storage units suffer problems with the use of traditional red laser scanners, because the red dot is difficult to see over a long distance or in bright daylight. This increases the risk

sampling across multiple Apollo MxFE on the same card or across different chassis. It also has the ability to support two-dimensional system synchronization (fanout and/or daisy chain architectures) for very large systems. Companion TxVGA and RxVGA solutions provide Apollo MxFE with +15dB of gain and the transition from single-ended to differential on Rx as well as differential to single-ended on Tx. This simplifies the connection to the RF front end. ADI is demonstrating Apollo MxFE at IMS 2023, June 13-15 in San Diego, California. Learn more at www. analog.com/IMS.

ams OSRAM’s new generation of color lasers features higher beam quality and allows for smaller power supply supply ams OSRAM (SIX: AMS), a global leader in optical solutions, introduces improved blue and green lasers based on a new generation of its diode emitter chip. The chip’s superior performance enables manufacturers to increase the value of laser modules and devices aimed at applications such as leveling and scanning. Enhancements made possible by the new lasers include a smaller power supply, a more homogeneous beam, and more efficient coupling to optical fiber. The improved PLT3 products are available in a TO38 Metal Can® package, and the PLT5 products in a TO56 package. Optical power output is 100 mW for the blue lasers, and between 10 mW and 50 mW for the green. Optical power output, wavelength options and beam shape are maintained from the previous generation of PLT3 and PLT5 products, but the new versions offer
