Laser diodes are semiconductor devices designed to emit highly concentrated, coherent light with robust precision and intensity. They resemble LEDs closely; however, a laser diode differs in terms of producing coherent lighting, meaning the light waves are all in phase. Also called semiconductor diode lasers, these devices produce strong light beams by turning the current passing through compact electrical and electronic circuits. They are compact, efficient, and are the most widely produced lasers. Our laser diodes are available in various wavelengths, indicated by lens colours, including red, blue, green, and infrared (IR). Each wavelength determines the use of a laser diode, such as a red laser diode commonly used in laser pointers and barcode scanners, and vice versa.
Why Buy Laser Diodes?
Buying laser diodes offers several advantages that make them a desirable choice for various modern technologies and applications. Their compact size, low power consumption, and highly focused beam of light enable precise targeting and efficient energy transfer. A laser diode is a cost-effective option and offers a long lifespan with a diverse range of wavelengths. Investing in quality laser diodes ensures better performance and improved system accuracy.
Check Our Range of Laser Diodes:
We offer surface-mount and through-hole laser diodes with different pin configurations (1, 2, 3, and 4 pins) to suit various mounting and control requirements. Our laser diode types include:
- VCSEL Laser Diodes – Vertical-Cavity Surface-Emitting Lasers (VCSELs) emit light to the surface of the chip perpendicularly, offering advantages in terms of manufacturing and packaging. A VCSEL is often used in applications like facial recognition, 3D sensing, and optical data communication.
- Continuous Wave (CW) Laser Diodes – CW laser diodes emit a continuous beam of light, as opposed to pulsed light. They are commonly used in applications such as laser pointers, barcode scanners, and laser cutting. A continuous wave laser diode is favoured for its reliability and ability to maintain consistent performance over extended periods.
Typical Uses of Laser Diodes:
Laser diodes are employed in a vast array of applications, including:
- Optical Storage
- Barcode Scanners
- Laser Pointers
- Medical Treatments
- Industrial Applications
- Telecommunications
- 3D Sensing and Facial Recognition.
