Visible Chirped Mirror TOD301-25.4-6.35

Overview

The UV/Visible Chirped Mirror 0fs² (Ultrafast Innovations TOD301) is a zero-GDD reference dispersive mirror engineered for ultrafast laser dispersion management, providing +0 fs² of group delay dispersion per bounce across the 650–720 nm operating bandwidth.

Applications

• Reference mirror for high-reflectance applications
• Delay-line use without dispersion impact
• Beam steering in dispersion-controlled setups
• Compressor null-mirror reference

Construction & Performance

Manufactured on a 25.4 mm diameter × 6.35 mm thick UVFS substrate with dielectric multilayer coating, R>95.0%@650-720nm. The mirror operates at 5° angle of incidence with p- and s-polarization compatibility. The coating provides exceptional layer density, low absorption losses, and long-term spectral stability — characteristics required for dependable performance in fs-laser oscillator and amplifier chains.

The 0.2 J/cm² damage threshold (specified at 800nm) supports typical ultrafast laser fluences. Compatible with research-grade and industrial fs-laser systems requiring controlled dispersion at this operating wavelength.

Storage & Handling

Operate at 25 °C, 40–60% RH. Clean only with >99% optical-grade ethanol and lint-free lens tissue using single-pass drag method. Avoid abrasive cloths and water.
