May 07, 2021· More economical laser to oscillate a single wavelength is a laser diode stabilizing the wavelength by using FBG. Figure 4 illustrates the structure outline. In this case, the laser cavity is composed of the HR coated end face of the active layer and the low reflectance FBG. In figure 4, the fiber core only is drawn.
