Principles of lasers kit


This solution enables students to gain practical experience in the investigation of optical amplification and lasers.

  • Suitable for courses in Optical Science and Photonics at undergraduate level and beyond



This solution allows detailed investigation of laser performance, output characteristics and dynamic response using a series of fibre ring lasers formed using an erbium doped fibre laser gain medium with feedback provided by various fused fibre couplers.

Learning objectives

  • EDF ring laser construction
  • Measurement of power/pump characteristic
  • Gain medium characterisation
  • Slope efficiency and lasing threshold
  • Effect of intra-cavity loss
  • Influence of output transmission ratio
  • Laser dynamics - relaxation, oscillations, exciation lifetime, laser onset time

Instruments may be required.  Please contact us for further information.
