Ultrabroadband detection of multi-terahertz field transients with GaSe electro-optic sensors: Approaching the near infrared
Year: 2004
Type: article
Abstract: Field-resolved detection of ultrabroadband infrared pulses is implemented with GaSe crystals. Via phase matching, we extend the detectable frequency range toward the near infrared (λ=2.5μm) and directly record transform-limited pulses as short as 28fs with a 3dB bandwidth of 41THz. The continuous tunability of the center frequency over a wide interval ranging from 31THz to the far-infrared is demonstrated using thick sensors.
