Main Results:

  • Achieved a multiwatt cw output power of 4.35 W.
  • Demonstrated a high slope efficiency of 22%.
  • Observed a 15-fold increase in output power and a 10-fold increase in slope efficiency compared to previous results.

Conclusions:

  • The developed quantum-dot semiconductor disk laser shows a substantial improvement in performance.
  • The use of a diamond heat spreader is effective for thermal management in high-power laser operation.
  • The laser's output power was limited only by the available pump power, indicating potential for further scaling.
