We have constructed a frequency-stabilized DFB laser compact module by using a vibrational-rotational absorption of acetylene molecules (named VRAM). The size of this device is about 4.5 cm long, 2 cm wide, and 2 cm high. Frequency stability to within 0.5 MHz peak/peak fluctuation was achieved at the 1.53159 μm wavelength.
