Abstract

A two-color laser beam separated by 587 cm⁻¹ is focused into a Raman cell pressurized with hydrogen. More than fifty rotational and vibrational lines are generated by a four-wave mixing-assisted stimulated Raman effect. By synchronously changing the laser frequencies, the overall tuning range is extended from the deep ultraviolet (247 nm) to the near infrared (771 nm) without any frequency gaps.
