We present a compact frequency-stabilized laser system locked to the Rubidium absorption line of a micro-fabricated reference cell. A printed circuit board (PCB) is used to carry all the components and part of the electronics, and low-temperature co-fired ceramic (LTCC) modules are used to temperature-stabilize the laser diode and the miniature Rubidium cell (cell inner dimensions: 5 mm diameter and 2 mm height). The measured frequency stability of the laser, in terms of Allan deviation, is <= 8 x 10(-10) for integration times of 10(3)-10(5)s. The current overall dimensions of the system are 70 x 40 x 50 mm(3), with good potential for realization of a frequency-stabilized laser module with few cm(3) volume.
