Laser Optics Summit

Online

June 11, 2025

The publishers of Photonics Spectra invites everyone to a summit on Laser Optics, a virtual event taking place on June 11, 2025.

Our Product Manager Dr.-Ing. Hansjörg Rohde will present the topic

Enabling High-Power Laser Performance through Advanced Optics

Registration to attend the event is free!

Abstract

As laser applications continue to advance toward higher power levels, optical components must evolve to meet stringent requirements for reflectivity, laser-induced damage thresholds (LIDT), and thermal stability.

Laser optics are key components in every laser processing system, especially in the high-power laser regime for applications like cutting, welding or additive manufacturing as well as various medical laser therapies. They guide the laser beam from the source to the workpiece while preserving the beam quality. Additionally, real-time process monitoring has become essential for ensuring quality assurance and traceability during production. As a result, high-precision diagnostic optics are playing a growing role in monitoring the laser-material interaction and enabling advanced process control. This requires optics with the highest reflectivity and damage threshold, which is currently driving the development of complex optical interference coatings.

Dr.-Ing. Hansjörg Rohde, product manager at LASER COMPONENTS, will highlight how modern optical coating technologies are being developed and optimized to address these growing challenges in diverse applications. Key topics include the selection of suitable coating methods, in-line process monitoring during the coating process and novel approaches such as post-deposition annealing to enhance coating performance and durability under extreme high-power laser operating conditions.

Manufactured By LASER COMPONENTS

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.
