Background:

External-cavity laser diodes (ECLDs) are crucial for tunable laser applications.
Traditional ECLDs often rely on diffraction gratings for wavelength selection.
Limitations in existing designs include complexity and stability issues.

Purpose of the Study:

Main Methods:

Development of a novel ECLD architecture incorporating an acousto-optic deflector (AOD).
The AOD functions as both a deflector and a diffraction grating for wavelength selectivity.
Characterization of the laser's wavelength scanning range and frequency response.

Main Results:

The proposed ECLD configuration demonstrates a wide wavelength scanning range of approximately 60 nm.
A maximum frequency response of 50 kHz was achieved.
The system exhibited a stable optical resonator with a constant cavity length.
Wavelength scanning results closely matched theoretical predictions.

Conclusions:

The novel ECLD design using an AOD offers a simple yet effective approach to wavelength selection.
The demonstrated performance metrics are suitable for advanced optical imaging.
Reproducible measurements indicate potential for applications in optical coherence tomography (OCT).
