Principle:
Excitation medium: Fiber-optic 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 (Nd) ions emit photons and produce laser.
frequency doubling crystal: in order to generate green light, the laser is usually generated in the infrared range first. This infrared laser is converted into green light by frequency doubling using nonlinear optical crystals (such as KTP crystals). 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, which can reliably transmit laser to the place where it needs to be processed.
Use:
Fiber-optic 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 rangefinder and 3d scanner.
laser cutting and carving: used for cutting and carving various materials, including metal, plastic and wood.
laser demonstration: used for projection and indication in meeting rooms, speeches and demonstrations.
laser pointer: a light source used in optical fiber communication and sensor systems.
Advantages and characteristics:
Visible light range: Green light is more sensitive to human eyes in the visible spectrum, so it is easier to be observed and recognized in many applications.
optical fiber transmission: optical fiber transmission allows long-distance laser transmission without sacrificing laser quality.
accuracy: the smaller wavelength of green laser gives it an advantage in some applications that require higher accuracy, such as laser cutting and engraving.
widely used: because of its characteristics in the visible range, fiber-optic green laser is widely used in various fields, including medical treatment, industry, communication and scientific research.
