Laser Diodes and Modules

DM200-01-4-9350-0-LC is a type of laser diode module commonly used in laser displays and photodynamic therapy. This article will detail its application area and working principle.

Application Field

The application areas of DM200-01-4-9350-0-LC mainly include laser displays and photodynamic therapy. In laser display technology, the module emits its laser beam and illuminates the surface of the display panel. Through the display panel, the motion of the beam can be observed, and the content of the image to be displayed can be presented in real time. While photodynamic therapy uses an external laser light source to irradiate and kill non-cancerous tissue for the purpose of medical treatment, modulate the light intensity and wavelength to achieve the therapeutic effect.

Working Principle

DM200-01-4-9350-0-LC is a direct-diode laser diode module, which means its operation is based on direct-diode lasing. Direct-diode lasing refers to the ability of the laser diode to directly convert electrical energy into laser beam without the need of a power supply. In order to achieve lasing, electrical energy is first converted into light energy, which is then amplified and emitted as a laser beam. The working energy of the DM200-01-4-9350-0-LC laser diode is converted into light energy by the optical gain medium in its cavity, which is further amplified by the optical feedback loop. The amplified light is then focused and collimated to form a laser beam, thus achieving the purpose of lasing.

Conclusion

DM200-01-4-9350-0-LC is a type of laser diode module that is commonly used in laser displays and photodynamic therapy. It is based on direct-diode lasing, which means it can convert electrical energy directly into a laser beam without the need of a power supply. The module has high efficiency, long life span, low cost and stable performance, making it an ideal choice for laser display and photodynamic therapy.
