Based on semiconductor lasers, the zero-expansion coefficient material is employed to build an ultra-stable cavity which is used to realize a narrow linewidth laser output. A laser diode and a grating are combined to form a Littrow structural external-cavity. After the first order diffraction, a small part of the output beam is used to lock the ultra-stable cavity which realizes the linewidth narrowing, and most of the output beam is injected into a tapered amplifier to achieve an amplification of optical power. A laser output with the wavelength of 1064 nm, output power of 290 mW and linewidth of 10 kHz is finally acquired. This technique can be applied in the area of atomic and molecular precision spectroscopy.
