Technical content

One-Box, Ultra-Stable, kHz Repetition- Rate, Ti:Sapphire Amplifier System Configured in a one-box, ruggedized, ultra-stable, compact platform, Libra features high performance comparable to advanced multi-box systems. The compelling, customer-value advantage and market success of Libra are enabled by key design innovations throughout and the Libra concept has proven itself in a wide range of scientific applications and demanding industrial settings. All Libra models are seeded by the Vitara-S oscillator, our hands-free, wide bandwidth oscillator. The design integrates Coherent’s newest HASS verified Revolution pump laser with the E-2 Engine module – Coherent’s thermally stabilized, high efficiency, regenerative amplifier platform that includes a unique, Ti:Sapphire rod geometry enabling simple, water-only cooling on all Libra models. Finally, a compact, stretcher and compressor support high power, short pulses with unsurpassed beam quality and stability. FEATURES & BENEFITS
