    • According to a first aspect, the present disclosure relates to a laser source for emitting radiation in a given emission spectral band, centered on a given emission angular frequency (ω), said the central emission angular frequency. The laser source comprises a laser cavity comprising a gain section having a known frequency dependent Group Delay Dispersion (the "Gain GDD"), and a GTI mirror arranged at one end of the gain section, having a known frequency dependent Group Delay Dispersion (the "GTI GDD"). The gain section and the GTI mirror are formed into a same laser medium, said laser medium having a known frequency dependent Group Delay Dispersion (the "Material GDD"), and the gain section and the GTI mirror are separated by a gap of predetermined width filled with a dielectric medium thus forming a two parts laser cavity. Further, the GTI GDD at least partly compensates the sum of the Gain GDD and the material GDD in said emission spectral band.
    • 根据第一方面,本公开涉及用于以给定发射角频率(ω)为中心发射给定发射光谱带中的辐射的激光源,所述中心发射角频率是中心发射角频率。 激光源包括激光腔,激光腔包括具有已知的与频率有关的群延迟色散(“增益GDD”)的增益部分和设置在增益部分的一端的GTI镜,具有已知的与频率有关的群延迟色散( “GTI GDD”)。 增益部分和GTI反射镜被形成为相同的激光介质,所述激光介质具有已知的与频率有关的群延迟色散(“材料GDD”),并且增益部分和GTI反射镜被预定的间隙 宽度填充电介质,从而形成两部分激光腔。 此外,GTI GDD至少部分地补偿了所述发射光谱带中的增益GDD和材料GDD的总和。
