053 μm. The absorption spectrum of ammonia was offered to exhibit the feasibility from the designed optical parametric oscillator process for spectroscopic measurements and fuel detection.We report with a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) based on the Kerr-lens-manner-locked Ti:sapphire laser as the pum
