JGS1 JGS2 UV Fused Silica Optical Window for High-Power Laser
Applications
MaterialFused Silica (Quartz Glass) The optical window, designated as JGS1 and JGS2, is crafted from
fused silica, also known as quartz glass. Fused silica is a
high-purity form of silicon dioxide (SiO2) that possesses
exceptional optical, thermal, and mechanical properties. This
material is renowned for its transparency across a broad spectral
range, making it ideal for applications requiring precise optical
performance. PropertyOptical Properties- High Transmittance: Fused silica exhibits high transmittance in the ultraviolet
(UV), visible, and infrared (IR) spectral regions. JGS1 and JGS2
grades are specifically engineered to offer optimal transmission
within specific wavelength ranges, making them suitable for
high-power laser applications.
- Low Absorption and Scattering: The material's low absorption and scattering characteristics
minimize energy loss and ensure clear, distortion-free optical
transmission.
Thermal Properties- High Temperature Resistance: Fused silica can withstand extremely high temperatures without
significant degradation, making it suitable for applications
involving high-energy laser beams that generate considerable heat.
- Low Thermal Expansion: Its coefficient of thermal expansion is relatively low, which
helps maintain dimensional stability and optical performance over a
wide range of temperatures.
Mechanical Properties- High Strength and Hardness: Fused silica possesses good mechanical strength and hardness,
making it resistant to scratching, abrasion, and other forms of
mechanical damage.
- Excellent Dimensional Stability: This material maintains its shape and size under various
environmental conditions, ensuring consistent optical performance.
FunctionThe primary function of the JGS1 and JGS2 UV fused silica optical
windows is to transmit high-power laser beams with minimal loss and
distortion. These windows serve as critical components in laser
systems, enabling efficient energy transfer and precise beam
control. They are designed to withstand the intense optical and
thermal loads associated with high-power laser applications,
ensuring reliable performance and long-term durability. ApplicationHigh-Power Laser Systems- Laser Beam Delivery: JGS1 and JGS2 optical windows are commonly used in laser beam
delivery systems, where they help guide and focus laser beams with
high precision.
- Laser Cavities and Amplifiers: These windows are also employed in laser cavities and
amplifiers, where they contribute to the stable operation and high
output power of laser systems.
- Optical Instrumentation: In optical instrumentation, they serve as critical components in
spectrophotometers, laser interferometers, and other precision
optical systems.
UV Laser ApplicationsDue to their excellent UV transmittance, JGS1 and JGS2 optical
windows are particularly suited for applications involving UV
lasers, such as lithography, microfabrication, and materials
processing.
