A synchronously pumped optical parametric oscillator (OPO) using a temperature tuned 90 degree phase matched LBO crystal is disclosed which provides a broad selection of output wavelengths. In one embodiment a Ti:sapphire pump source having a cavity length matched to the OPO cavity length pumps a cavity with an LBO crystal located at the cavity waist of the cavity mode. Resources are included to, tune the OPO to a desired wavelength, repetitively scan through a series of desired wavelengths, and adjust the cavity length to obtain a synchronous pumping condition and diagnose a wavelength at which the OPO is operating. A frequency doubled beam in the LBO crystal is generated as a substantially collinear alignment beam.
