Broadly tunable mode-locked HgCdTe lasers

We report tunable cw mode-locked laser action from synchronously pumped HgCdTe lasers. 4–8-μm-thick liquid phase expitaxial layers lasing at λ=1.2 and λ=1.73–2.0 μm are longitudinally pumped by a neodymium: yttrium aluminum garret (Nd:YAG) laser. Peak output powers of 50 W using a chopped pump beam,...

Zusammenfassung:	We report tunable cw mode-locked laser action from synchronously pumped HgCdTe lasers. 4–8-μm-thick liquid phase expitaxial layers lasing at λ=1.2 and λ=1.73–2.0 μm 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 μm. Nearly bandwidth-limited pulses of 6-ps duration have also been obtained. Tuning from λ=1.82 to 2.0 μm via the Burstein–Moss shift has been accomplished on a single epilayer by varying the loss in the external cavity.
