We report on the development of a compact packaged semiconductor laser capable of spectroscopy applications at 689 nm. The key component is an optical isolator that is small enough to fit inside a package that is compatible with standard 14-pin butterfly packages. We present a threshold current of 33 mA, a forward voltage of 2.5 V at 50 mA, long term reliability study for over 12,500 hours, a relative intensity noise below -145 dBc/Hz, and a linewidth of 2 MHz. The relative intensity noise and the frequency noise spectra verify continuous-wave lasing and frequency stability of the packaged laser.
