Znse Output couplers (partial reflectors), Rear Mirrors (Silicon)for High power CO2 lasers

Co2 laser focus lens are made of USA imported CVD Zinc Selenide,which is produced by DOW chemical. USA made CVD ZnSe with sided AR-coated, whose main function is to decrease or eliminate the reflective light from lens, prisms, etc. and thus to increase these components transmittance rate and decline or eliminate stray light. Our focus lenses have advantages over than those of others, such as low laser power absorption rate, enduring high laser power density, stable surface coating film and wiping resistance. In CO2 laser industry common working band, 10.6 um, our laser lens transmittance rate is 99.8%.

As a most economical transmission laser focus components, laser focus lens is widely used in laser heat treatment, welding, cutting and infrared radiation collection. In order to obtain satisfactory performance and achieve the purpose that the surface of the lens should be towards the direction of imputed light beam towards the conjugate distance the longer end.

The output Coupler usually has reflectance in the range 30% to 70%.In order to optimize power and spatial profile of the laser beam, the output coupler and end mirror have optical surfaces with request curvature.

The output coupler is typically composed of Znse in order to minimize absorption and thermal distortion while transmitting a high-power laser beam. The end mirror usually has reflectance 99.5%
