Dispersing Prisms meet ultrashort pulse laser systems' needs.

May 27, 2015

Depending on alignment, Ultrafast Dispersing Prisms may introduce negative or positive dispersion. Negative dispersion compensation allows effects of other dispersive optical elements to be cancelled. In high-power, ultrafast applications, introducing positive dispersion elongates pulse in time to mitigate risk of damage to optical components. RoHS-compliant, 25.4 x 25.4 mm products, polished to minimize reflection loss, come in 3 substrates and support intracavity and extracavity use. Read More
