AMS OSRAM, a world-leading provider of optical solutions, recently announced the launch of the latest blue-green laser diode - PLT5 488HB_EP, specifically developed for the field of life sciences, to expand its high-power laser product line. This diode emits laser with a wavelength of 488nm, and its brightness is five times higher than that of the previous generation. It has achieved significant breakthroughs in performance and energy efficiency compared to earlier models. The improvement of these performance indicators is crucial for reliable analysis in life science research and diagnostic applications such as DNA sequencing and flow cytometry. Its high performance can also facilitate rapid and accurate detection, greatly expanding the diagnostic possibilities in large laboratories. This product represents a breakthrough in semiconductor laser technology and will help medical institutions, hospitals and care centers build more compact and cost-effective diagnostic systems.

The PLT5 488HB_EP blue-green laser diode developed by AMS OSRAM achieves an output power of 300mW. Its optical performance is five times higher than that of the previous generation product, and the electro-optical conversion efficiency is increased by more than 40%. The significant increase in optical output power can achieve higher measurement accuracy and accelerate the processing speed of biological samples. The 488nm laser diode is a key device in modern diagnostic and scientific research fields, widely used in blood, serum, plasma analysis, as well as flow cytometry and DNA sequencing scenarios. In the application of genetic diagnosis, relying on laser penetration of biological samples, the sequence of DNA constituent unit nucleotides is precisely determined by taking advantage of their specific light absorption and emission characteristics. Higher-performance laser diodes can significantly enhance the timeliness and accuracy of analysis results.

Winfried Schwedler, the marketing manager of AMS OSRAM, emphasized: "Our 488nm wavelength laser diode achieves reliable and precise analysis with outstanding optical performance, while effectively reducing power consumption. It has become the preferred solution for high-precision requirements such as laboratory-level genetic testing, clinical diagnosis scenarios, and forensic biological evidence analysis." This device stands out among similar products with its low noise characteristics, wide modulation bandwidth and top-notch beam quality.

The blue-green spectral band has a highly efficient excitation efficiency for commonly used fluorescent dyes in diagnostic equipment such as flow cytometers and blood testing devices. The PLT5 488HB_EP is specially designed for precise wavelength regulation of ±2nm and high light intensity output of 300mW, perfectly meeting the strict requirements of the life science field for outstanding color rendering performance and precise measurement. Its high modulation bandwidth characteristic enables fine control of light intensity, significantly improving signal quality while enhancing the timeliness of the analysis process.

The new type of laser diode also features low thermal resistance, ensuring stable operation even under high-temperature conditions. This device integrates photodiodes to monitor output power and contains ESD protection diodes, effectively enhancing the durability and high reliability of the product.

In addition to life science research, this blue-green laser diode has demonstrated outstanding potential in a wide range of application scenarios. For example, by expanding the color gamut range of stage and venue lighting, highly visually striking dynamic light effects can be produced. In the field of fluorescence microscopy technology, its specific wavelength of 488nm can significantly enhance the imaging contrast and break through the analytical limit of traditional light sources for microstructure. These cutting-edge performances make the PLT5 488HB_EP a strategic addition to AMS OSRAM's high-power laser diode product matrix.

At present, AMS OSRAM has more than 2,000 valid patent assets in the global laser diode field and has always maintained a leading position in the industry *.
