Theoretical analysis shows that the number of working wavelength will increase with the increment of the harmonic number of the harmonic blazed grating.
理论分析表明,谐闪耀光栅谐振波长数目随谐波数增加而增加,因此可用于多波长斜光束的高效耦合;

The needed frequency of the blazed grating is in inverse ratio of the incident wavelength. The longer the wavelength, the lower the grating frequency is.
