Coated Laser Optics

Dielectric coatings are one of our core competencies at Laser Components. We primarily deposit customer-specific optical coatings onto almost any substrates. E-beam technology, also referred to as physical vapor deposition (PVD), ion-assisted deposition (IAD), and ion beam sputtering (IBS) are the coating processes currently available.

AR Coatings

AR coatings to minimise reflections.

Coated Laser Optics

All of LASER COMPONENTS‘ AR coatings are optimized for high power lasers and are available for the wavelength range from 193 nm to 3000 nm. Both the bandwidth (depending on the wavelength) and the effectiveness of the coating can be influenced by the various designs and different coating materials. Thus the optimal coating for each application can be made available.

MgF2 Single Layer AR1

This coating is the simplest type of AR coating. It consists of a single MgF2 layer with a thickness of l/4. This coating is best suited, above all else, for materials with a high refractive index, such as for sapphire or SF6 glass.

Optimized AR Coatings

The majority of AR coatings are optimized for one wavelength. They are often used on materials such as BK7 or fused silica. There is a difference between U-AR coatings, which have a wider spectral effect, and V-AR coatings, which are more narrow banded. The U-AR coatings also have a smaller back reflection, but the coating costs are somewhat higher. Both versions are multi-layered, dielectric coatings that are available for all central wavelengths from 193 nm to 3000 nm.

Multiple AR Coatings

Special AR coatings are needed for frequency-multiplied laser systems. These coatings exhibit optimal transmission not only for the fundamental wavelength, but also for additional harmonic wavelengths.

Double AR coatings such as 1064 + 532 nm or 800 + 400 nm are the most popular. Another established standard coating is one which features a special design for all common Nd:YAG laser lines. This coating is optimized for the wavelengths

1064 + 532 + 355 + 266 nm.

All versions are multi-layered, dielectric coatings that are suitable for high power laser systems. Upon request, special designs can be produced for the desired substrate.

Broadband AR Coatings

If optimal AR coatings for a wide wavelength range are required, then special multi-layered, dielectric coatings are used. With the help of a single coating the transmission for a wide wavelength range can be enhanced.

Using different coatings it is possible to cover the entire wavelength range from 193 nm to 2100 nm. Special versions or customer-specific ranges can also be manufactured.

All BBAR coatings are available as a standard version for angles of incidence of both 0° and 45°. Other angles of incidence are available upon request. At an angle of incidence of 45°, it is possible to optimize for different polarizations (u-pol, s-pol, or p-pol).
