Active and Passive Glasses for Lasers
We offer a wide variety of solutions to engineers seeking active and passive glass-based materials for laser applications. These materials run the gamut from neodymium-doped laser and special filter glasses for use as laser pumping cavity and diagnostic filters to ultra-stable glass-ceramic for laser applications requiring the utmost in precision.

SCHOTT Advanced Optics offers a wide variety of materials for use in high precision laser applications with excellent properties, including:
- Platinum-free
- High quality
- High homogeneity
- Good processing behavior
|
Active and passive glass-based materials are most often used in commercial and industrial energy solid-state lasers, as well as for the medical industry in cosmetic, eye and laser surgical procedures.
|
We offer active laser glass with phosphate and silicate base compositions.
|
Glass for laser applications can be supplied as slabs, cut blanks, polished rods, plates, and disks.

Phosphate compositions for high energy applications
|
LG750, LG760, LG770 are types of glasses that have been developed to meet the needs of the high-energy solid-state laser community.
All three types of glass exhibit high laser cross-section, low nonlinear refractive index, and athermal characteristics. All are available in a form free of all metallic platinum particles and other inclusions that can cause laser damage.

Phosphate-based laser glass for high power and ultra-short pulse applications
|
APG1 and APG2 have enhanced thermal mechanical properties desirable in high average power applications. The broad emission bandwidth of these materials has been utilized in femtosecond regime laser systems. The lower gain cross-section and long low concentration emission lifetime have made these glasses of interest in applications limited by amplified stimulated emission and/or intended for excitation by diode lasers. These types of glass are available in a form free of all metallic platinum particles or other damaging inclusions.

|
Silicate composition
|
LG680 is a classic laser glass that features a high cross-section, high ultraviolet transmission, and high resistance to solarization. This glass is commonly employed in high repetition rate solid-state laser systems.

Active glass for integrated optic applications
|
IOG1 was developed specifically for compatibility with known sodium ion exchange technologies for fabrication of active guided wave structures. IOG2 was developed specifically for high gain applications not using ion exchange technology. These types of glass are used in applications with such rare earth ions as erbium, ytterbium, praseodymium, and their combinations.

|
Passive Glass
|
IOG10 was developed specifically for compatibility with known ion exchange technologies for the fabrication of passive guided wave structures.
|
|
Laser Cavity Materials |
S7010N and S7005 are samarium-doped glasses that block the 1.06 mm wavelength and UV pump light from neodymium lasing elements, such as Nd:YAG or Nd:glass rods and slabs. S7000 is a clear, cerium-doped glass that serves as a UV cutoff material.

ZERODUR® Zero Expansion Glass Ceramic
|
|
ZERODUR® glass ceramic exhibits a near-zero coefficient of thermal expansion over a fairly wide temperature range. It possesses exceptional long-term dimensional stability and is thus suitable for precision applications within laser systems.
|
|
Our quality control is based on 100% control of geometrical shape and internal quality. The parts are inspected during all stages of fabrication in addition to an intensive final inspection at the end of the process. We measure internal quality with accurate measurement of the parts with microscope and stress measurement setups according to the "de Senarmont" method. High energy lasers are also used for damage testing.
