Blue laser pointer diode model

Popular blue laser pointer diodes include 450 nm, 455 nm, and 460 nm models, with varying power outputs and packaging options.

Common Blue Laser Diode Modelsams OSRA

M PLPT9 450LC_E: A high-power blue laser diode with a wavelength of 455 nm, delivering up to 5. 5 W optical power in a robust TO90 metal can package. It features high wall-plug efficiency (~43%) and is suitable for industrial, medical, and high-demand applications.

Roithner RLP-450 Series: Direct-emitting 450 nm laser diodes for pointer applications, with output power ranging from 1 mW to 50 mW. These diodes include Automatic Power Control (APC) for stable output and are housed in polished metal cases, making them ideal for presentations and scientific use. Berlin Lasers 460 nm Pointer: Uses a 460 nm diode with low-power options like 1 mW and 5 mW, providing a stable and reliable beam for lectures, conferences, and laser displays.

Key Considerations

Wavelength: Blue laser diodes typically range from 415 nm to 495 nm, with shorter wavelengths offering smaller spot sizes and stronger material absorption, which is beneficial for high-resolution imaging or data storage applications. Power Output: Pointer diodes usually range from 1 mW to 50 mW, while industrial or high-power diodes can reach several watts. Ensure the power rating complies with safety regulations for your intended use.

Packaging: Common packages include TO-can (TO18, TO56, TO90) for robust mounting and thermal management, and integrated pointer housings for handheld use. Applications: Blue laser diodes are used in pointers, scientific research, microscopy, laser displays, and industrial processing. High-power diodes can also be converted to white or other colors using phosphor conversion.

For purchasing, suppliers like Mouser Electronics and RPMC Lasers offer datasheets, inventory, and technical support for selecting the appropriate blue laser diode for your application.
