Pulse And Delay Generator in Optical Research: The GFT1604
This technical publication in Photoniques explores the “red thread” of optical glass development—from the fundamental physics of refractive indices to the high-performance materials required for modern augmented reality. Central to these advancements is the need for precise timing and diagnostic tools that can keep pace with rapid optical pulses.
The GFT1604: A Cornerstone for Laser System Integration
As research pushes the boundaries of picosecond laser systems, the Greenfield Systems GFT1604 emerges as an essential pulse and delay generator for complex experimental setups. It addresses the rigorous timing requirements of modern optics by providing:
- High-Resolution Timing: Offers 100 ps resolution for delays up to 10 seconds, with an optional 1 ps resolution for ultra-precise applications.
- System-Wide Synchronization: Designed to synchronize a full array of devices, including pump-lasers, Q-switches, and Pockel cells.
- Low Jitter Performance: Ensures that repetitive or single pulses are delivered with extremely low jitter, maintaining the integrity of the laser oscillator’s reference signal.
- Flexible Output Options: Features 4 independent channels (expandable to 8) with adjustable amplitudes from 1.5 V to 50 V to suit various laboratory needs.
Why Timing Matters in Optical Innovation
The paper highlights that achieving perfection in imaging—whether in high-end microscopes or AR glass wafers—requires managing nonlinear dispersion and ultra-short pulses. For researchers utilizing these advanced glasses, the GFT1604 provides the necessary control interface via Ethernet or USB, allowing for remote, automated synchronization of the entire optical path.
By integrating the GFT1604 into your workflow, you gain the picosecond-level control required to master the “interplay of challenges” inherent in cutting-edge optical glass research.
