Laser Products

Our high reflectance ceramic cavities, used within laser reflectors, versus more traditional metal and polymeric parts, provide extended life-time with reduced maintenance downtime, greater efficiency and reflectance as well as increased uniformity and thermal stability.

Feedthroughs used in gas lasers feature brazed-joint design combined with the chemical stability which allows CO₂ laser manufacturers to use their systems more intensively, reduce the downtime and operating cost.

We manufacture a wide range of products for laser applications designed to work together and simplify your supply chain, including:

Components for imaging, sensing and measurement equipment

Laser Ceramics Questions

Why are ceramics used as laser materials?

Ceramics are specified because of ceramics’ high reflectance at critical wavelengths, e.g. 98%+ reflectance at 1064nm, coupled with exceptional and uniform thermal stability, low electrical loss, resistance to solarisation and oxidation, corrosion resistance to gases and fluids (such as fluorine compounds, CO₂, cooling fluids and cleaning fluids), cleanliness, and hardness. The high reflectance is obtained by a combination of the material properties, microstructure and controlled porosity of the material.

What are the advantages of ceramic laser components over other materials?

While other materials (such as polymers, polished aluminium, and gold or silver-plated fused silica or glass) can demonstrate the required reflectance at a desired wavelength, they often lack sufficient additional attributes which detrimentally impacts long-term laser quality (e.g. thermal stability, corrosion resistance, cleanliness, durability during maintenance). Furthermore, the reflectors made out of alumina ceramic, e.g. Sintox™ AL , have high reflectance over a wide range of wavelengths, e.g. 98% reflectance across the wavelength range 500 – 2000nm.

How are ceramics used in laser components?

Ceramics components reflect light to concentrate the light energy to amplify an intense, coherent, collimated beam of light at a specific nominal wavelength, a “laser beam.” Because of the high-energy needs of some of these systems, ceramics are often used as electrical feedthroughs for their high electrical resistivities.

What wavelengths are Morgan's Sintox AL ceramic reflectors optimised for?

Sintox AL alumina reflectors provide greater than 98% reflectance across the wavelength range of approximately 500 to 2000nm. They are particularly suited to solid-state Nd:YAG lasers (1064nm) and intense pulsed light (IPL) devices operating from 530 to 1000nm. Their reflectance is highly uniform across the cavity surface, improving beam quality and consistency.

Why are ceramic waveguides preferred over metallic waveguides in CO2 lasers?

Alumina and aluminium nitride ceramic waveguides offer a combination of properties that metal waveguides cannot match: high electrical resistivity to confine the discharge, excellent thermal stability under continuous operation, resistance to the corrosive gas mixtures used in CO2 lasers, and hardness that withstands mechanical cleaning during maintenance. These properties combine to give substantially longer service intervals.

Can Morgan manufacture custom-sized laser tubes and reflectors?

Yes. We produce laser tubes and reflectors in a wide range of standard and custom sizes. Our extrusion and precision machining capabilities, combined with our in-house glazing and surface finishing processes, allow us to tailor products to specific laser system designs. We work with laser OEMs at the design stage to optimise component geometry for maximum performance.
