  • How do LEDs emit laser light

    How do LEDs emit laser light

    Light-emitting diodes (LEDs) produce light (or infrared radiation) by the recombination of electrons and electron holes in a semiconductor, a process called "electroluminescence". An LED (Light Emitting Diode) converts electricity into light, whereas a laser amplifies light to produce a coherent, monochromatic beam. However, they differ significantly in their emission characteristics, energy efficiency, working principles, applications, and safety considerations. So what's the difference between LED and Laser diodes? Let's find out the details.

  • How to adjust the wavelength of a laser diode

    How to adjust the wavelength of a laser diode

    How can the wavelength of a laser diode be tuned? Laser diodes are commonly tuned by changing their temperature, for example with a thermoelectric cooler. This modifies the gain spectrum and shifts the output wavelength, typically achieving a tuning range of a few nanometers. This is where laser diode temperature tuning becomes the engineer's most powerful tool turning an out-of-spec component into a precision light source without replacing a single part. Why do Wavelengths Shift in Laser Diodes? Laser diodes differ fundamentally from gas lasers in how their emission. The first method is to influence the laser gain medium in such a way that the wavelength of maximum gain is changed, and the output wavelength changes accordingly (Figure 1). by altering the angle of incidence on the grating. Optimized diode control will reduce.
