Near IR OPA unit

Near IR OPA unit

Optical Parametric Amplifier. Use with a Sirah dye laser for powerful output in the Near Infrared 1.4-4.2µm region.

A frequency doubled, injection seeded Nd:YAG laser is used to pump a PrecisionScan dye laser, operated in the red spectral range. The dye laser output beam and a fraction of the residual 1064nm pulse from the Nd:YAG are mixed in a temperature stabilised LiNbO3 crystal for difference frequency generation.

The generated IR beam passes a second LiNbO3 crystal, pumped by the remaining residual 1064nm pulse and used as an optical parametric amplifier.

The OPA amplifies the initial IR beam and generates signal and idler beam. Due to injection seeding, the resulting bandwidth is governed by the configuration of the dye laser resonator.
