We report tunable cw mode‐locked laser action from synchronously pumped HgCdTe lasers. 4–8‐&mgr;m‐thick liquid phase expitaxial layers lasing at &lgr;=1.2 and &lgr;=1.73–2.0 &mgr;m are longitudinally pumped by a neodymium: yttrium aluminum garret (Nd:YAG) laser. Peak output powers of 50 W using a chopped pump beam, and a cw mode‐locked average output power of 5.6 mW, have been achieved at a wavelength of 1.2 &mgr;m. Nearly bandwidth‐limited pulses of 6‐ps duration have also been obtained. Tuning from &lgr;=1.82 to 2.0 &mgr;m via the Burstein–Moss shift has been accomplished on a single epilayer by varying the loss in the external cavity.
