ams OSRAM, a global leader in intelligent sensors and emitters, has launched a new laser diode with an output power of 300 milliwatts (mW) and a wavelength of 488 nm, making it ideal for life science research such as DNA sequencing.

ams OSRAM has unveiled a new cyan laser diode that is up to five times brighter than previous products.

This new product, PLT5 488HB_EP, emits light at a wavelength of 488 nanometers (nm), and has five times higher optical performance and more than 40% higher efficiency than the existing model.

This is expected to contribute to significantly improving the precision of life science research and diagnostic technologies such as DNA sequencing and flow cytometry.

The new laser diode delivers superior output power of 300 milliwatts (mW), enabling faster and more accurate processing of biological samples with improved optical output.

In life science research, the 488 nm wavelength is essential for examining a variety of biological samples, including blood, serum, and plasma analysis.

In particular, during the DNA sequencing process, nucleotides absorb and emit light in a unique way, improving the accuracy of base sequence analysis. More powerful lasers are expected to accelerate analysis speeds while increasing reliability, further expanding their utility in medical and research facilities.

“This 488nm laser diode offers excellent beam quality, low noise and a wide modulation bandwidth, making it ideal for precision-critical research and diagnostic applications,” said Winfried Schwedler, Marketing Manager at ams OSRAM.

Cyan lasers have many applications beyond life science research.

In stage and stadium lighting, it expands the color range to create vivid visual effects.

Fluorescence microscopy utilizes specific wavelengths to visualize fine cellular structures more clearly.

Additionally, the high modulation bandwidth can improve signal quality and analysis speed, further enhancing research and diagnostic accuracy.

The new diodes from ams OSRAM feature low thermal resistance for stable operation at high temperatures, and feature an integrated photodiode for output control and ESD protection for enhanced reliability and robustness.

ams OSRAM holds over 2,000 patents worldwide and maintains unrivalled market leadership in laser diode technology.
