DFG 9800/9850

A High Repetition Rate Source for Ultrafast Spectroscopy

The DFG 9800/9850 are accessories for our OPA 9800 and OPA 9850 Optical Parametric Amplifiers. Both the 9800 DFG and the 9850 DFG extend the tuning of our OPAs into the mid-IR range. When combined with a Coherent all-solid-state ultrafast system, consisting of the Verdi pump laser, Mira Optima 900 Ti:S oscillator, RegA 9000 regenerative amplifier, and OPA 9800 or OPA 9850, the DFG 9800/9850 allows continuous tuning from 2.55 µm to >10 µm. This level of operation makes the DFG 9800/9850 the industry’s only high repetition rate source for ultrafast spectroscopy in the mid-IR range.

• Tunable solid-state source for mid-IR operation
• Compatible with our OPA 9800 and OPA 9850 optical parametric amplifiers
• Repetition rates up to 300 kHz
• Ease of wavelength tuning
