Description
Non-collinear optical parametric amplifier (NOPA) belongs to ultrafast laser technology and generates high-power, frequency-tunable pulses by mixing a pump beam and a white-light seed at an angle within a nonlinear optical crystal. Our home-built NOPA features a dual-beam configuration: one path utilizes a green pump to generate tunable infrared output, while the other employs an ultraviolet pump to produce visible and ultraviolet light. The output pulses are temporally broadened due to dispersion and nonlinear processes. To enhance the temporal resolution of NOPA, a pair of SF10 prisms is installed to provide negative group delay dispersion (GDD) to compensate for the broadening. On this poster a detailed analysis of our pulse compression for the infrared light, demonstrating a minimal pulse duration of 27.2 ± 0.3 fs, will be presented.
