Principle:
Excitation medium: fiber green laser usually uses Nd:YVO? Materials such as yttrium vanadium oxide or Nd:YAG (yttrium aluminum oxide) are used as the excitation medium. When excited, Nd ions emit photons and generate laser light.
Frequency doubling crystal: In order to generate green light, laser is usually generated in the infrared range first. This infrared laser is converted into green light by using nonlinear optical crystals (such as KTP crystals) through frequency doubling. This process is called frequency doubling or frequency doubling.
Optical fiber transmission: the generated green light is transmitted through optical fiber. Optical fiber has flexibility and low loss, and can reliably transmit laser to the place where it needs to be processed.
Use:
Fiber green laser has a wide range of applications, including but not limited to:
Laser display: used for curtain wall decoration, advertising signs and other laser display applications.
Laser therapy: In the medical field, especially in ophthalmic surgery, green laser is used to treat retinal diseases, such as diabetic retinopathy.
Laser ranging: Green laser is widely used in rangefinders and 3d scanners.
Laser cutting and carving: used for cutting and carving various materials, including metal, plastic and wood.
Laser demonstration: used for projection and indication of meeting rooms, speeches and demonstrations.
Laser pen: light source for optical fiber communication and sensor system.
Advantages and characteristics:
Visible light range: green light in visible light spectrum is more sensitive to human eyes, so it is easier to be observed and recognized in many applications.
Optical fiber transmission: Optical fiber transmission can realize long-distance laser transmission without sacrificing laser quality.
Accuracy: The wavelength of green laser is small, which has advantages in some applications that require high accuracy, such as laser cutting and engraving.
Widely used: Fiber green laser is widely used in various fields, including medical treatment, industry, communication and scientific research because of its characteristics in the visible range.
