We present an ultra-narrow-linewidth laser designed based on optical self-injection locking to a miniaturized whispering gallery mode resonator. The measured instantaneous linewidth of the laser is at sub-Hertz-level, making it suitable for precise energy-level excitation in quantum technology applications.
