Michael Mayr, Product Manager at AMS OSram, said: "This new blue laser diode is a major step forward in blue laser technology, providing our customers with a powerful and efficient solution in demanding applications. With its superior optical power, high performance and compact design, the 455 nm laser diode greatly optimizes industries for further development of laser-based applications."The PLPT9 450LC_E has been designed to produce up to 5.5 watts of optical power at 455 nanometers. The electro-optical efficiency of this new laser diode is significantly improved, typically up to 43%. With its high output power and high efficiency, it performs well in industrial and medical applications where optical performance is highly required. In addition, the product offers a wavelength split of 2 nanometers, allowing customers to precisely select the right device for applications with stringent wavelength requirements. Its rugged TO90 metal package offers low thermal resistance to further enhance reliability and stability.
Diverse ability to convert
Wavelength conversion is a key element of blue laser technology, which greatly expands its versatility and application range. With the phosphor conversion process, blue laser diodes are capable of producing high-power white light for applications where high lighting quality is required, such as spotlights with narrow beam angles. In addition to white light, blue lasers can also be converted to other colors, such as red, green and orange, through a phosphor conversion process. In this process, different phosphor materials emit different colors when excited by a blue laser. This flexibility enables a variety of colors to be produced in a precise and efficient manner to meet the specific needs of different industries. Applications such as stage lighting and specialty lighting can significantly benefit from the ability to produce a broad spectrum of colors, significantly enhancing their functionality and performance. For example, in microscopy applications, the ability to produce specific colors combined with narrow beam angles can dramatically improve imaging contrast and detail clarity.
Projection and other applications
The PLPT9 450LC_E relies on its powerful high optical power to make the image bright and clear, showing excellent performance in the field of laser projection. With its high efficiency and stable and reliable characteristics, the product can fully meet the diverse needs of industrial users and become one of the key components of high adaptability in various technical solutions. Whether it is a large projection or a complex and detailed laser display, this blue laser diode can perform well and bring a significantly improved visual experience to multiple platforms.
In addition to the wide range of applications in the field of projection, blue lasers also perform well in material handling applications such as engraving and welding. With their superior accuracy and reliability, blue lasers are ideal for industrial applications such as fine marking.
PLPT9 450LC_E has been officially unveiled at Munich Shanghai Optical Fair 2025.
