Witryna8 lut 2024 · VCS894.6-DP is a planar device, with single-longitudinal-mode emission at 894.6nm (the wavelength corresponding to the D1 transition line of Cs atoms). The device offers high mode stability, with side-mode suppression ratio (SMSR) of 25dB and narrow spectral linewidth of 40MHz, as tested at 80°C and 2mA. WitrynaA further discussion of these injection- locked states and spectra will be presented in chapter three of this thesis. By using the injection locking technique, the linewidth of a multi-mode FP laser can be reduced from its free running linewidth of ~100 GHz to as low as the narrow linewidth of the master laser, ~100 kHz. hip hop chicken 20735
