V-COATINGS CVI Laser V-type Coatings are the best choice for a single laser or multiple, closely spaced DOUBLE-V AND TRIPLE-V COATINGS Coating Traces . Examples are the principle argon laser Below the existing paragraph add: lines at 488nm and 514nm, the neodymium transitions Specifications for the standard CVI Laser Optics in a variety of host materials at 1047 – 1064nm and their Double-V and Triple-V Coatings (0° AOI): harmonics, and the individual excimer laser lines. Said X R ≤ 0.3% at 1064nm standard coatings are available for most laser lines. X R ≤ 0.6% at 532nm X R ≤ 1.5% at 355nm CVI Laser Optics will manufacture V-type AR coatings for wavelengths from 193nm to 2100nm. Center wavelengths with the aforesaid range can be optimized Material Properties for specific angles of incidence and polarizations by request.

Standard CVI Laser Optics V-type AR coatings on Fused Silica, , Suprasil, and N-BK7 have a damage threshold of 15J/cm2 at 1064nm, 20ns, 20Hz. Typical performance can often exceed 20J/cm2. Other

coating designs are available to increase and/or prioritize Optical Specifications the need for high laser damage threshold. Damage thresholds for AR coatings on N-SF11 and similar are limited not by the coating, but by the bulk material properties. Our damage testing has shown a damage threshold for N-SF11 and similar glasses to be 4J/cm2.

When ordering, be sure to specify the following: X Wavelength X Substrate Material X Angle of Incidence X X Fluence in J/cm2

Specifications for the standard CVI Laser Optics V-type AR Coating (≥ 266nm): X R ≤ 0.25% at 0°, ≤ 0.1% typical X R ≤ 0.75% for 45° P-Polarization X R ≤ 1.0% for 45° Unpolarized X R ≤ 1.3% for 45° S-Polarization

Other coating designs and methods may be applied to significantly reduce reflectance. These designs may be applied by request.

BROADBAND MULTILAYER HEBBAR™ COATINGS ANTIREFLECTION COATINGS HEBBAR coatings exhibit a characteristic double- Broadband antireflection coatings provide a very low minimum reflectance curve covering a spectral range of reflectance over a broad spectral bandwidth. These some 250 nm or more. The reflectance does not exceed advanced multilayer films are optimized to reduce 1.0%, and is typically below 0.6%, over this entire range. overall reflectance to an extremely low level over a broad Within a more limited spectral range on either side of spectral range. the central peak, reflectance can be held to well below 0.4%. HEBBAR coatings are relatively insensitive to There are two families of broadband antireflection angle of incidence. The effect of increasing the angle of coatings from CVI Laser Optics: BBAR and HEBBAR™. incidence (with respect to the to the surface) is to shift the curve to slightly shorter wavelengths and to BBAR-SERIES COATINGS increase the long wavelength reflectance slightly. These CVI Laser Optics offers seven overlapping broad band coatings are extremely useful for high numerical- antireflection (BBAR) coating designs covering the (low f-number) and steeply curved surfaces. In entire range from 193 nm to 1600 nm. This includes very these cases, incidence angles vary significantly over the broad coverage of the entire Ti: region. The aperture. BBAR coatings are unique in the industry by providing both a low average reflection of ≤ 0.5% over a The typical reflectance curves shown below are for N-BK7 very broad range and also providing the highest damage substrates, except for the 245 – 440 nm and threshold for pulsed and continuous laser sources 300-500 nm coatings which are applied to fused silica (10J/cm2, 20 ns, 20 Hz at 1064 nm and 1MW/cm2 cw at substrates or components.

Typical performance curves are below apply only to substrates with refractive indices shown in the graphs for each of the standard range ranging from 1.47 to 1.55.
