Tm:YAG Crystals

Tm (thulium-doped yttrium aluminum garnet) is a solid-state laser material doped with thulium ions, used in mid-infrared lasers, especially suitable for medical, industrial, and scientific research fields.

Tm crystals are based on yttrium aluminum garnet (YAG) and achieve laser emission by doping with thulium ions (m³⁺). The main laser wavelength of this material is 1.9 μm, making it suitable for pump laser sources such as diode lasers. laser from Tm has good beam quality and high efficiency, and can operate stably over a wide temperature range. Additionally, the absorption peak of Tm crystals biological tissues is close to that of water, making it particularly effective in medical applications such as laser surgery and tissue cutting.

Advantage:

1. Mid-infrared laser emission: The laser wavelength matches the absorption characteristics of biological tissues, making it suitable for medical applications.

2. Efficiency: Good laser conversion efficiency, suitable for high-power applications.

3. Excellent beam quality: Produces high-quality laser beams, suitable for precision processing.
