Deuterated Arginine Phosphate (DLAP) is a type of nonlinear crystal used in ultrafast laser applications, particularly for optical parametric amplification (OPA). DLAP is a deuterated form of Arginine Phosphate (LAP) crystal, which is similar in structure to KDP.
DLAP has several advantages over LAP for OPA applications. Its deuterated nature allows for a higher nonlinearity and a lower photorefractive damage threshold, which is important for high-power laser applications. DLAP also has a higher damage threshold than KDP, making it a promising candidate for high-energy ultrafast laser systems.
In optical parametric amplification, DLAP can be used to amplify ultrafast laser pulses with high efficiency, and to generate tunable laser radiation in the near- to mid-infrared region. DLAP can also be used for frequency conversion, harmonic generation, and as a nonlinear element in laser-based experiments.
