Abstract :
Summary form only given. Optical parametric oscillators (OPOs) are well suited for the generation of high power ps and fs light pulses in the near infrared region up to 4 /spl mu/m using KTP or its isomorphs. The spectral region of the mid infrared can, in principle, be covered using such nonlinear crystals as AgGaS/sub 2/, AgGaSe/sub 2/ and ZnGeP/sub 2/. This has been demonstrated with pulsed ns OPOs and mode-locked ps-OPOs. We report what is to our best knowledge the first demonstration of femtosecond continuous-wave (CW) mode-locked operation of an AgGaSe/sub 2/-OPO in the mid infrared spectral region.
