They have Secondary Harmonic Generator (SHG) option for their pump laser. They have DPSS pumped Ti:Sa laser and dye lasers, diode lasers etc. You can discuss the exact wavelength of the first harmonic ( primary wavelength) which has to be doubled using crystals like Lithium Niobate,BBO, KDP which they have at present in their laboratory to the required SHG wavelength that you are looking for.

Good luck.
