Effectively Limiting ASE: A Simple Solution for Fiber Lasers
Samuel Gouin
Product Line Manager
The ASE Shield by indie is a groundbreaking solution for high-power fiber lasers and amplifiers, addressing the critical issue of Amplified Spontaneous Emission (ASE). ASE can significantly limit output power, especially when the lasing or amplifying wavelength is far from the active fiber’s maximum gain. By effectively suppressing ASE at its source, the ASE Shield enables fiber laser manufacturers to dramatically increase output power, stability, and overall system robustness.
At the heart of the ASE Shield lies indie’s exclusive chirped tilted Fiber Bragg Grating (CTFBG) technology. This innovative approach not only effectively suppresses ASE but also safeguards systems against parasitic lasing and unwanted signal interference. The result is a cutting-edge component that enhances the performance and reliability of high-power fiber lasers and amplifiers, pushing the boundaries of what’s possible in laser technology.
With the ASE Shield, manufacturers can overcome traditional power limitations, opening new possibilities for applications requiring high-power, stable laser output.
Key Features and Benefits
Power Handling:
With its all-fiber design, the ASE Suppression Filter can reliably operate at power largely exceeding alternative solutions.
Low Insertion Loss:
Low insertion losses for highly efficient filtering without compromise.
Value:
With its all-fiber design and low insertion losses, the ASF offer lower costs and considerably simplifies system design.
Reliable:
The ASE Shield, engineered to outlast fiber lasers, exemplifies indie’s proven expertise, with thousands of FBG units successfully deployed over the past decade.
Partnership:
indie will work through the entire product development process, from prototyping to mass production.
