Laser Materials and Components

The laser glass product portfolio that SCHOTT offers can cover the whole spectrum of active and passive laser glasses, and we divide our glass materials into three main product variants to help customers focus on the application and the glass best suited to it.

1 µm Silicate and Phosphate-based Glasses 1 µm Silicate and Phosphate-based Glasses

These laser glasses are suited to high-fluence laser glass components, which operate without laser-induced damage. SCHOTT’s platinum-particle-free melting allows for more advanced manufacturing options and customization.

CHARACTERISTICS

These include large volume laser slabs in apertures up to 400 mm and in large quantities, which enable high-energy storage for inertial confinement fusion programs. They are also suited to zig-zag slabs and large diameter laser rods with the highest optical quality and homogeneity possible, which can help facilitate high-output power of materials processing laser systems.

 

YOUR ADVANTAGES

  • High laser cross section
  • Low nonlinear refractive index
  • Athermal characteristics
Eye-safe 1.5 µm Phosphate Glasses
Eye-safe 1.5 µm Phosphate Glasses

This family of ‘eye-safe’ laser glasses are erbium-ytterbium doped, phosphate-based laser glass used in flashlamp-pumped and diode-pumped solid-state laser systems, which are used increasingly in defense and medical applications.

CHARACTERISTICS

Phosphate glasses generally offer higher solubility of rare earth dopants, meaning that the amount of active ions can be significantly increased. Examples of glasses in this group are LG-940 Erbium-Ytterbium-Chromium-Cerium doped glass, LG-950 Erbium-Ytterbium doped phosphate laser glass (produced specially for the European market) and LG-960 Erbium-Ytterbium doped phosphate laser glass, which offers an improved thermomechanical figure of merit.

 

YOUR ADVANTAGES

  • Suited to cost-effective solid-state laser systems.
  • Potential for increased load and/or repetition rates.

Cerium- and Samarium-doped Filter Glasses

SCHOTT offers specific materials tailored for use as laser-pumping cavity filters used in a number of configurations, including plates, close-fitting cylindrical sleeves, and cylindrical water jackets. These filter glasses absorb undesired pumping light in the UV and IR ranges, preventing solarization of the laser glass.

CHARACTERISTICS

By absorbing the Nd laser light, these filters reduce amplified spontaneous emissions and eliminate parasitic oscillation, thereby increasing the efficiency and power of the laser.

 

YOUR ADVANTAGES

  • Adapted edge cladding glasses on request.
  • Possibility for chemical strengthening in order to increase resistance to breakage due to thermal shock.
  • Completely customized designs are possible.
