Ho:YLF (Holmium doped yttrium lithium fluoride) – Laser Crystal – Gain Medium – Customized products
Ho: YLF crystal product, also known as holmium doped yttrium fluoride lithium crystal. It is a laser product with excellent comprehensive performance. It is widely used in industry, medical treatment, and scientific research. The product has the characteristics of a low nonlinear refractive index, low thermal, constant optical value, and long service life of 5I7 energy level. It can be used in remote sensing and pollutant monitoring solid laser products.
Note:
$100 is a deposit, not the final price of the product. Please contact us for price if needed.
Features:
High emission cross-section
Long upper laser level lifetime
Naturally birefringent material
Efficient Q switch operation (up to 37 mJ per pulse)
The low value of dn/dT leads to a weak thermal lensing
The continuous wave output of the YLF laser can be up to 21W
