Tunable laser materials comprising solid-state blended polymers

Conventional laser materials cannot flexibly adjust their emission color across the full optical spectrum (from blue to infrared); their complex design makes sensor system integration and production more difficult and costly.

• The laser color can be adjusted simply by changing the ratio of two polymers, covering blue to infrared wavelengths.
• This material is ready for use in applications like health monitoring, environmental sensing, and tissue imaging, enhancing device flexibility.
• The simple design removes the need for multiple different materials, making multi-wavelength laser system integration and production easier and cheaper.

• Enables broad wavelength tuning from blue to infrared, outperforming available materials.
• Laser color can be easily set by changing the polymer blend ratio, increasing application flexibility.
• Simplifies the design of laser sensor systems, reducing complexity and saving costs.
• Easily scalable for industrial use and portable devices.

• Multi-wavelength laser sensors for health, environmental or medical detection.
• Optical components for portable analyzers and smart devices.
• Cost-effective laser sources for education, demonstration or research.
• Adaptable for next-generation, high-sensitivity spectrometers.
