| HGTR-KTP Crystal |
 |
| Product introduction: |
|
Gray track damage is the most serious damage to which conventional flux-grown KTP crystal is susceptible.
Bairay's hydrothermal-grown KTP has high damage threshold and high ability to anti gray track. It is extremely suitable for laser system applications requiring high power, high efficiency and/or durability where regular flux-grown KTP crystals will suffer from gray track damage.
