Summary

This summary is machine-generated.

We demonstrate coherent amplification of a single-stripe diode laser using a 100-mW laser diode array. This technique dramatically narrows the output spectrum and spatial distribution, achieving a single diffraction-limited mode.

Area of Science:

Optics and Photonics
Laser Physics

Background:

Diode lasers are widely used but often suffer from broad spectral output and poor spatial beam quality.
Achieving high-power, spectrally narrow, and spatially coherent laser output is crucial for many applications.

Purpose of the Study:

To investigate the coherent amplification of a low-power diode laser using a commercial laser diode array.
To assess the spectral and spatial characteristics of the amplified output beam.

Main Methods:

Utilized optical feedback from a Fabry-Perot cavity to spectrally narrow and stabilize the input laser light to <300 kHz.
Employed a 100-mW continuous-wave (cw) laser diode array for amplification.
Analyzed the amplified beam's spectral and spatial properties.

Main Results:

Achieved amplification of the input laser light to ~90 mW.
The amplified beam retained the narrow spectral characteristics (<300 kHz) of the input light.
The output beam exhibited a single diffraction-limited spatial mode, indicating coherence across the entire 100-microm array width.
Observed dramatic narrowing of the free-running laser array's output spectrum and spatial distribution when seeded with the input light.

Conclusions:

Demonstrated a viable method for coherent amplification of diode laser light using a laser diode array.
The technique effectively transfers spectral and spatial coherence from a low-power source to a higher-power output.
The results support a simple quantitative model of the amplification process.
