Astrella

Product catalog summary

Overview
Astrella is a high-performance, kHz amplifier designed for femtosecond research, offering a combination of performance, reliability, and affordability. It is part of the industrial revolution in ultrafast science, providing industrial-grade laser reliability.

Design and Testing
The Astrella system is designed and manufactured using advanced stress testing methods, including HALT (Highly Accelerated Lifetime Testing) and HASS (Highly Accelerated Stress Testing), conducted in a customized test chamber. This ensures enhanced reliability and lifetime.

Industrial Design and Testing Cycle
The cycle includes capturing failure/performance changes, root cause analysis, and corrective action, ensuring unmatched industrial laser experience and reliability.

Vertical Integration
In-house production of diodes, crystals, and critical optics ensures superior supply and quality control.

Key Components

Sealed Stretcher/Compressor: Features robust, thermally stabilized design with a controlled clean environment, ensuring stable pulse width and minimized power degradation.
Robust Regenerative Amplifier: Built on the STAR platform for maximum stability, efficiency, and beam quality, with a thermally-stabilized baseplate and unique Ti:Sapphire slab-geometry for simple cooling.
Vitara Oscillator: Known for reliability, it integrates a Verdi pump laser and is manufactured with quality control of critical optics.
Revolution Amplifier Pump: Offers performance margin over design specifications, building on the strengths of its predecessor.

Reliability and Support
Each Astrella sub-system is HASS-verified before integration, ensuring unmatched reliability and lifetime. The system offers pulse widths of either <35 fs or <100 fs, with pulse energy specified to >7 mJ at 1 kHz. It is supported by a global network for rapid, expert scientific support, with service plans offering up to 5 years of coverage and certified spare parts available for faster delivery.

Contact Information
Coherent provides contact details for support across various regions including the United States, China, France, Germany, Italy, Japan, Korea, Netherlands, Taiwan, and the United Kingdom.
