SCHOTT Advanced Optics has a long history of making high performance laser glass (i.e. NIF) from raw glass to finished component with outstanding properties:
- Platinum-free
- High homogeneity
- Consistent high quality of laser glass, polish and coating
- AR and HR coatings with high laser damage threshold exceeding 1.5 GW/cm2
|
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. Here some examples in detail:
- High peak power operation
- High average power operation
- Laser-range finding applications
- Medical lasers such as for dermatological use
|
We offer active laser glass with phosphate and silicate base compositions.
|
- Cut blanks or slabs
- Coated rods or slabs

| Eye-safe laser glasses |
LG910 and LG930 are Er, Yb doped phosphate glasses for use in flash-lamp or diode pumped laser systems. They have a very low dn/dT, good athermal properties and very high emission cross section. Typical applications are laser range finding and medical lasers.

Phosphate compositions for high energy applications
|
LG750, LG760, LG770, LG910, LG930 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.

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 micrometer 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.
|
|
Quality control is based on statistical process control starting from incoming material inspection to a rigorous final inspection of the finished component. Glass properties are measured for every melt. Measurement instruments include a broad range of interferometers, spectrophotometers, physical property test systems, vision systems, and laser test beds.
