History of High Power LED Laser Technology

The concept of LED (Light Emitting Diode) dates back to the early 20th century, but it was not until the 1960s that the first LED was developed. Initially, LEDs were used for indicator lights and low-power applications. However, with advancements in semiconductor technology, the development of high power LED lasers began in the late 1990s. The breakthrough came with the invention of the Vertical Cavity Surface Emitting Laser (VCSEL) by researchers at the University of California, Berkeley. This technology paved the way for the development of high power LED lasers with superior performance and efficiency.

Technology Behind High Power LED Lasers

High power LED lasers are based on the principles of optoelectronics, which involve the conversion of electrical energy into light. These lasers utilize a semiconductor material as the active medium, typically made of gallium nitride (GaN) or aluminum nitride (AlN). The key components of a high power LED laser include the laser diode, lens, and heat sink. The laser diode is the heart of the system, generating the laser light through the process of stimulated emission. The lens focuses the emitted light into a tight beam, enhancing its intensity and directionality. The heat sink dissipates the heat generated during the operation, ensuring the longevity and reliability of the laser. High power LED lasers offer several advantages over traditional laser technologies, such as lower cost, smaller size, and higher efficiency. Additionally, they emit light in a specific wavelength, making them suitable for various applications.
