A laser system where the output can be selected from two or more different wavelengths of output laser light.
The system comprises a laser capable of having at least two different wavelengths of laser light resonating in the cavity simultaneously. One of the frequencies is generated by a Raman crystal which shifts the frequency of light generated by the lasing medium. A tuneable non-linear medium, such as LBO, is provided in the cavity for selectively frequency converting at least two different wavelengths of light.
The conversion may be SHG, SFG or DFG for example. A tuner is provided to tune the non-linear medium to select the wavelength to convert. Temperature tuning or angle tuning of the non-linear medium can be used. A Q switch may also be provided in the cavity. The output laser beam can be used for treatment, detection or diagnosis of a selected area on or in a subject and can be used in ophthalmological and dermatological fields.
