ED-LASE: Principles of Lasers

The ED-LASE kit 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.

Experiments Examine:

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