Prevention of coherence collapse in diode lasers by dynamic targeting

Area of Science:

• Optics and Photonics
• Laser Physics

Background:

• Coherence collapse is a phenomenon that can degrade laser performance.
• Uncontrolled lasers may exhibit unstable output power and broad linewidths.

Purpose of the Study:

• To investigate a novel dynamic targeting technique for laser stabilization.
• To demonstrate the prevention of coherence collapse in lasers.

Main Methods:

• Numerical simulations were employed to model laser dynamics.
• The new dynamic targeting technique was applied to a laser system prone to coherence collapse.

Main Results:

• The dynamic targeting technique successfully prevented coherence collapse.
• The stabilized laser operated with a consistently small linewidth.
• A stable maximum output power was achieved.

Conclusions:

• The novel dynamic targeting technique is effective in stabilizing laser operation.
• This approach offers a viable solution for lasers susceptible to coherence collapse.
• Achieving stable laser output and narrow linewidths is possible with this technique.
