1030nm Chirped Mirror PC1611-25.4-6.35

Overview

1030nm Chirped Mirror -150fs² is a high-negative-dispersion mirror designed for negative GDD compensation in chirped pulse amplification chains across the 850–1200 nm operating bandwidth.

With -150 fs²/bounce, this mirror compensates typical intracavity material dispersion (5–10 mm of fused silica) in a manageable bounce count, balancing ripple control with practical compressor footprint. Multilayer coating optimized to maximize negative GDD per reflection while preserving high reflectance — the standard approach for fs-laser CPA compressor design.

Applications

• Yb:YAG regenerative amplifier post-compression
• industrial fs-laser dispersion management for materials processing
• ultrafast micromachining beam delivery
• high-average-power thin-disk multi-pass amplifiers

Construction & Performance

Manufactured on a 25.4 mm diameter × 6.35 mm thick UV fused silica (UVFS) substrate with ion beam sputtered (IBS) dielectric multilayer coating, >99.7% reflectance specified as R>99.7%@850-1200nm. The mirror operates at 5° angle of incidence with p-polarized light. The IBS coating provides exceptional layer density, sub-ppm absorption losses, and long-term spectral stability — characteristics required for dependable performance in high-average-power amplifier chains.

1030 nm Yb-band IBS dielectric coating with optimized GDD flatness ensures consistent dispersion control under typical fs-laser operating conditions. Compatible laser systems include Yb:YAG thin-disk amplifiers, Yb:KGW oscillators (Light Conversion Pharos, Carbide), and Yb:fiber chirped pulse amplifiers.

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.
