Paper report on the frequency noise investigation of the Extended Cavity Diode Laser (ECDL), working at 729 nm. The ECDL will be used as an excitation laser for the forbidden transition in a trapped and laser cooled 40Ca+ ion. For that an Hz of sub-Hz level linewidth is required. We present the experimental design for linewidth narrowing and frequency noise analysis. The linewidth is first narrowed with a phase lock loop of the ECDL onto a selected component of an optical frequency comb where the frequency noise was suppressed with a fast electronic servo-loop controller that drives the laser injection current with a high bandwidth.\n
