PCF amplifier

précédent suivant

Based on its expertise in laser design and photonic crystal fiber interfacing, ALPhANOV developed a technology to build turn-key 100-Watt-class monolithic laser amplifiers with superior stability.

 

 

 

This technology relies on a Yb-doped microstructured fiber architecture. It can be tailored to meet specific requirements in terms of power, temporal regime and other functionalities.

 Stability

 

 1000hrs 

 Optical interfaces

 Input interface

 High power FC/APC connector, bare fiber

 

 Output interface

 End-cap, SMA connector, collimator and/or isolator

 Pump specification

 Number of diode ports

 2 or 6 (on-demand)

 Pump diodes

 Up to 60W, CW or pulsed

(*) ALPhANOV recommends a gain of 17-20dB or less. A tap coupler with a detection circuit is implemented to prevent self Q-switching.

 

Special requests:

  • Pre-amplifying on-demand
  • Specific fiber amplifier developments on-demand
  • Possibility to build a complete laser architecture with oscillator and SHG/THG module
