A transversely chirped volume Bragg grating (TCVBG) is used as an external cavity diode laser to realize a simple, narrow line width, wavelength stability and continuous tunable external cavity diode laser. The wavelength stability and narrow spectral width characteristics of the external cavity diode laser using TCVBG is demonstrated. The wavelength tuning characteristics and power characteristics of TCVBG is analyzed. Experimental results indicate that the wavelength of the diode laser is locked and the linewidth is narrowed sharply under the effect of TCVBG external cavity. The continuous tuning output spectra is achieved by moving laterally relative position TCVBG. The continuous tuning range from 800 nm to 815 nm is implemented. The spectral line width (full width at half maximum, FWHM) is less than 0.3 nm. An output power of 2.01 W is also obtained and the power stability is less than 1.5% over the investigated tuning range.
