US Patent 7756175 Pumped semiconductor laser systems and methods

A method for emitting laser radiation includes: emitting first laser radiation using a first laser, wherein said first laser is a laser diode; receiving the first laser radiation by a second laser comprising CdSe(1-x)Sx (cadmium selenium sulfide, cadmium selenium, or cadmium sulfide), wherein x is between 0 and 1, inclusively; and responsive to receiving the first laser radiation by the second laser, emitting second laser radiation by the second laser via the CdSe(1-x)Sx; wherein the second laser radiation has a wavelength between 487 nm and 690 nm; and wherein the wavelength of the second laser radiation is responsive to the value of x, which represents the relative concentration of selenium and/or sulfur.
