Application of the solid solution Cd(x)Hg(1-x)Ga(2)S(4) as a nonlinear optical crystal

We review the optical properties of the mixed crystal Cd(x)Hg(1-x)Ga(2)S(4) , propose three potential applications to which various physical properties can be tailored, and present experimental results of femtosecond optical parametric amplification in the mid IR from 5.5 to 8mum with 1.25-mum pumping by a 1-kHz Cr:forsterite regenerative amplifier.
