LASER COMPONENTS Germany - Laser Optics

Hard dielectric coatings for laser optics

Laser Optics

Since 1986, the name LASER COMPONENTS has stood for top quality in optical coatings for laser technology. Renowned large laser manufacturers rely on our optics in a wide range of applications.

In specially developed high-vacuum systems with electron beam sources, we vaporize both our own substrates and those supplied by customers. Rush orders are handled by our 24-hour service upon request.

The production department has seven coating systems, including two ion sputtering systems for the latest generation of laser optics. Our specialties include glass parabolic mirrors for disk lasers, adaptive optics, and Gaussian mirrors.

Fiber assembly

Since 1995, we have been developing and producing custom-made optical fibers in series production. Our fiber-connector combinations include large-core HCS fibers and gradient index fibers.

Other products, such as sterile patch cords, SMA high-performance connectors with free-standing fibers, or light bundles made of POF, have been developed in recent years. Our focus lies on customer-specific special solutions for the medical, laser systems, sensor technology, industrial, aerospace, and automotive markets.

Fiber coating

Anti-reflective (AR) coatings on fiber ends reduce coupling losses. LASER COMPONENTS GmbH offers a variety of AR coatings:

Single AR for one wavelength
Dual AR for two wavelengths, or
Broadband AR for a wavelength range.

Fiber stripper

For medical applications involving optical fibers, we have developed MediStrip, a sterilizable fiber stripper that allows the fiber to be re-prepared during surgery. Cleaning and sterilization procedures have been validated by an independent testing laboratory.

Electronics manufacturing

With our own electronics manufacturing facility, we can respond flexibly and, above all, quickly to customer requests. Here, circuit boards for controlling PLDs and APDs are designed and prototypes are manufactured before they go into mass production, and customer-specific products are manufactured individually or in small series.

PLD and APD Modules

Our PLD modules enable reliable control and safe operation of pulsed laser diodes (PLDs). They are highly flexible thanks to continuously adjustable output power and pulse length and are particularly suitable for product development.

APD modules from LASER COMPONENTS consist of a low-noise Si or InGaAs avalanche photodiode with preamplifier and integrated HV power supply plus temperature compensation. They detect even the smallest amounts of light quickly and reliably.

Our temperature-stabilized high-voltage modules for APDs and PIN detectors are available for high voltages.

Photon Counters

Since 2010, LASER COMPONENTS has been manufacturing and qualifying complete single-photon counters with COUNT® modules. They have high quantum efficiency and very low dark count rates.

The Geiger Mode Silicon Avalanche Photodiode, developed in-house by the LASER COMPONENTS Detector Group, is one of the lowest-noise devices on the market and impresses with its excellent quantum efficiency in the blue and red spectral range.

Laser Modules

Under the brand name FLEXPOINT®, we design and manufacture thousands of laser modules in a wide variety of designs every year.

FLEXPOINT^® laser modules consist of a cw laser diode or a DPSS (diode pumped solid state) module, as well as optics adapted to the application, and electronics. Various housings, wavelengths or power levels, and controllers with digital or analog modulation increase the flexibility of the miniature laser system. All FLEXPOINT® laser modules are CE certified and RoHS compliant. The laser class of each individual module is specified in accordance with DIN EN 60825-1.

With our 3D CAD system, we can simulate a complete laser module in advance. LASER COMPONENTS offers customers the option of having a laser module developed that is precisely tailored to their application and then manufactured in series.

Products

Aspherical lenses correct aberrations, which in monochromatic light include image sharpness errors and distortion.

A typical application of these lenses is the focusing of a collimated beam onto an optical fiber.

Brewster plates are used to separate s- and p-polarized light.

Brewster plates have a rectangular shape and are inserted at a specific angle of incidence to the laser beam. Light that is polarized parallel to the plane of incidence/reflection is completely transmitted at Brewster’s angle, whereas about 50 % of s-polarized light is transmitted.

Cavity end mirrors are used to generate the laser beam in the resonator.

Resonator end mirrors, also known as cavity mirrors, are designed to have high reflectivity at the desired laser wavelength in order to maximize the efficiency of the laser.

ROUND AND RECTANGULAR CYCLINDER LENSES ARE USED TO CREATE LINES / BEAM EXPANSIONS IN ONE DIRECTION.

We offer plano-concave and plano-convex cyclindrical lenses in rectangular, square, and round form.

DIAGNOSTIC BEAM SPLITTERS FOR PROCESS MONITORING

Dichroic mirrors separate or combine two or more beams of different wavelengths in the desired ratio and enable process monitoring on the operating level in several wavelength ranges, as well as beam diagnostics. Their complex design enables multiple transmission and reflection ranges.

combine or separate two or more beams with different wavelengths.

Customized dichroic mirrors that are suitable for your individual application are manufactured upon request.

The degree of reflection slopes from the center of the optic in a Gaussian distribution.

Gaussion mirrors are used in unstable resonators - mostly as meniscus lenses with an integrated wedge to avoid back reflections despite of antireflection coatings.

Optimized for high-power lasers with intense pulse energies or high average powers

Mirrors for high-power lasers are high-precision optical components that direct or focus the laser beam. Thanks to a dielectric coating, the mirrors reflect the laser beam efficiently and withstand the high thermal load caused by the laser energy.

Protective windows are used during laser material processing to protect against material splashes.

Protective windows are the last optics to be used in front of the work area. They protect high-quality laser optics from material splashes during cutting, welding, drilling, structuring, marking and additive manufacturing. Protective windows are available in a variety of shapes and qualities.

FOR SPLITTING INTO ONE OR MORE DEFINED PARTIAL BEAMS.

When working with lasers, it is often necessary to split a laser beam into two or more defined partial beams. There are a variety of beam splitters for these applications, with different advantages and disadvantages. Dielectrically coated beam splitters have a high laser damage threshold.

Transmissive Plano-Parallel Plates WITH MINIMAL DISTORTION, SCATTERING OR ABSORPTION

Optical windows for laser applications are flat, transparent substrates made of materials with excellent optical properties. They are usually optimized to provide maximum transmission in a specific wavelength range providing low reflection and absorption at the same time.
