Frequency-stabilized DFB laser module using 1.53159 mu m absorption line of C/sub 2/H/sub 2/

A frequency-stabilized distributed-feedback (DFB) laser module using the vibrational-rotational absorption of acetylene molecules is discussed. 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 mu m wavelength.<
