Injection-seeded intracavity terahertz optical parametric oscillator

Not Accessible

Your library or personal account may give you access

Abstract

We report a terahertz (THz) source continuously tunable over 20GHz with a linewidth <100MHz (close to the transform limit of 110ns pulses) and settable anywhere in the range of 13THz. The source consists of an injection-seeded intracavity THz optical parametric oscillator, which exhibits the benefits of lower threshold and enhanced efficiency and power over a similar extracavity device. Linewidth control was achieved with <1mW of seed laser power and THz pulse energies of >5nJ observed with up to 68% downconversion of the pump wave. Spectroscopy of the 1.4969THz carbon monoxide absorption line was performed to verify linewidth and demonstrate tuning capability.
