Abstract :
We developed a new compact and massive bulk Er-Yb laser and locked its emission wavelength to various lines of the /sup 13/C/sub 2/H/sub 2/ (/spl nu//sub 1/+/spl nu//sub 3/) rovibrational transition at around 1.54 /spl mu/m. Peak to peak frequency stability of the locked laser was /spl plusmn/40 kHz over an observation time of 500 s.
