YAG laser crystal fiber transmittance 80% 25μm 100μm can be used for fiber optic sensors

Short Description:

YAG is the abbreviation of Yttrium Aluminium Garnet. YAG fiber usually refers to the fiber made of yttrium aluminum garnet as the gain medium. This kind of fiber is widely used in the field of laser technology, and it is an important optical component that can produce high power and high beam quality laser output.
Single crystal yttrium aluminum garnet (YAG) fiber, which has better physical properties than amorphous silica, and has a higher output power. These fibers support a whole new range of applications, including material processing and medical lasers. There are several ways to develop high power (several kilowatts) lasers. Bulk single crystals are widely used for their excellent thermal conductivity, efficiency and mechanical resistance.

YAG optical fibers have the following main characteristics

1. Beam quality: The key aspect of Nd: YAG is better than fiber lasers is the quality of the beam. Essentially, the laser marking beam quality is a specific term for the M2 value, usually given in the laser technical specification. The M2 of a Gaussian beam is 1, allowing for a minimum spot size relative to the wavelength used and the optical element.
2. The best beam quality in Nd: YAG laser marking system is 1.2 M2 value. Fibre-based systems typically have an M2 value of 1.6 to 1.7, which means that the spot size is larger and the power density is lower. For example; The peak power of the fiber laser is in the range of 10kW, while the peak power of the Nd: YAG laser is in the range of 100kW.

3. Basically, better beam quality will result;
· Small line width
· Clearer outline
Higher marking speed (due to high power density), as well as deeper engraving.
A good beam quality can also provide better focal depth than a laser with a lower beam quality.

The main application ways of YAG fiber include the following aspects

1. Laser: YAG fiber has a wide range of applications in lasers of different bands, such as 1.0 micron, 1.5 micron and 2.0 micron band fiber lasers. In addition, YAG fiber is also used in high-power monocrystalline fiber ultra-short pulse amplification technology, especially in the femtosecond oscillator output ultra-short pulse amplification.

2. Sensors: YAG fiber shows great potential in the field of sensors because of its unique optical properties, especially in extreme temperature and radiation environments.

3. Optical communication: YAG fiber is also used in the field of optical communication, using its high thermal conductivity and low nonlinear effect to improve the laser power output potential.

4. High power laser output :YAG fiber has advantages in achieving high power laser output, such as Nd:YAG single crystal fiber to achieve continuous laser output at 1064 nm.

5. Picosecond laser amplifier: YAG fiber shows excellent amplification performance in picosecond laser amplifier, which can achieve picosecond laser amplification with high repetition frequency and short pulse width.

6. Mid-infrared laser output: YAG fiber has a small loss in the mid-infrared band, and can achieve efficient mid-infrared laser output.

These applications demonstrate the broad potential and importance of YAG fiber in multiple fields.
