Abstract
The invention provides a laser system () wherein the output may 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 tunable non-linear medium (), such as LBO, is provided in the cavity for selectively frequency converting at least one of the at least two different wavelengths of laser light. The conversion may be SHG, SFG or DFG for example. A tuner () is provided to tune the non-linear medium to select the particular 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 opthalmological and dermatological fields.
