LaserNGN - Fiber gain modules

The tapered optical fiber at the heart of the gain module is based on our low photodarkening core chemistry and features a distinctive and proprietary refractive index profile. The result is a TMI-free operation at up to 100 W of output average power, with excellent beam quality and good polarization maintenance.

The LaserNGN product family includes two gain modules, the LaserNGN-56 and LaserNGN-40mini. Both modules are optimized for high peak power and high average power applications, and integrate everything needed to handle power, high thermal load and high peak fluence pulses.

LaserNGN-56 Features:

• 10/125 input fiber for ease of splicing
• Output fiber core diameter: 56 µm
• Single-mode like output
• Large end cap termination
• Cladding mode stripper
• Robust, water-cooled construction
• Pumping configuration: modules are available in counter-propagating pumping architectures with or without a pump injection module.

LaserNGN-40mini Features:

• 10/125 input fiber for ease of splicing
• Output fiber core diameter: 40 µm
• Single-mode like output
• Large end cap termination
• Cladding mode stripper
• Robust, water-cooled construction
• Compact design
• Pumping configuration: co-pumping

Advantages of the LaserNGN-56 and LaserNGN-40mini:

• High nonlinear threshold
• High peak power
• High average power
• High gain
• Excellent beam quality
• Broadband gain bandwidth
• Excellent optical-to-optical slope efficiency
