YAG laser is generated when a YAG (yttrium-aluminum-garnet) crystal is excited. A YAG crystal is regarded as one of the most excellent one because it shows various oscillation forms and also presents excellent optical characteristics.

- Transmittable through an optical fiber.
The YAG laser light is transmitted using optical fibers, resulting in easy remote processing and simplified system.
The laser can be set up easily in factory automated system. A single unit offers simultaneous multipoint welding (power-sharing delivery welding) and time-scheduled welding (time-sharing delivery welding)
At present, no optical fiber can transmit a high-power CO₂ laser light for laser processing.

- Invisible light.
Laser light is near infrared light of 1064 nanometer (1.064 micrometer) wavelength; it is invisible.

- Suitable for micro-processing.
The YAG laser does not diverge but proceeds straight. As the wavelength (1.06μm) is one tenth of CO₂ laser wavelength (10.6μm), the YAG laser can be focused to a fine beam, leading to micro-processing.

The features of the laser processing and machining are:
Not only metal but also resin can be laser processed.

1. Ultra-precision processing.
2. Less deformation of workpiece owing to non-contact machining.
3. Owing to the absence of electrode, welding electrode maintenance which is needed in resistance welding is not required.
4. Easy processing of different metals, non-conductive materials.
5. No heat distortion owing to short period of joining time.

It varies depending on such as output, function. The smallest 10W-rated one ML-2030B with a single mechanism costs you 3,450 thousand yen (main unit only).

Yes, power density increases. If energy is constant, the smaller the projection area is, the higher the density is; however, you must use caution in the fact that only smaller amount of laser energy can be inputted to smaller area of the end of fiber.
