Abstract
A volume Bragg grating (VBG) has a narrow wavelength. The wavelength is changed by changing an angle of the VBG or a temperature of the VBG. Thus, the present invention has a narrow wavelength, a bright laser, a simple system and an adjustable reflection for a wide application to laser systems.
Claims14
A volume Bragg grating laser mirror device, comprising:
