PULSED DYE LASER ACCESSORY Mid-Infrared Generation (MIR) The mid-infrared generation unit (MIR) is designed to generate powerful laser pulses in the wavelength range from 4.8 to 11 μm. It is operated with a Quanta-Ray ® Nd:YAG pump laser, a PrecisionScan dye laser equipped with either a single or a double grating resonator with 1800 lines / mm gratings, and an optical parametrical amplifier unit (OPA-NIR). PRINCIPLES A Quanta-Ray 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 and a fraction of the residual 1064 nm pulse from the Nd:YAG laser are mixed in a LiNbO 3 crystal for difference frequency generation. The generated IR pulse passes a second LiNbO 3 crystal pumped by the remaining 1064 nm pulse, and is tuned to act as an optical parametrical amplifier. The OPA amplifies the initial IR pulse and generates signal and idler frequency. The difference frequency of these two pulses is generated in a AgGaSe 2 crystal. Due to injection seeding, the resulting linewidth is determined by the configuration of the dye laser oscillator.

PULSED DYE LASER ACCESSORY
Mid-Infrared Generation (MIR)The mid-infrared generation unit (MIR) is designed to generate powerful laser pulses in the wavelength range from 4.8 to 11 μm. It is operated with a Quanta-Ray® Nd:YAG pump laser, a PrecisionScan dye laser equipped with either a single or a double grating resonator with 1800 lines / mm gratings, and an optical parametrical amplifier unit (OPA-NIR).
PRINCIPLES
A Quanta-Ray 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 and a fraction of the residual 1064 nm pulse from the Nd:YAG laser are mixed in a LiNbO3 crystal for difference frequency generation. The generated IR pulse passes a second LiNbO3 crystal pumped by the remaining 1064 nm pulse, and is tuned to act as an optical parametrical amplifier. The OPA amplifies the initial IR pulse and generates signal and idler frequency. The difference frequency of these two pulses is generated in a AgGaSe2 crystal. Due to injection seeding, the resulting linewidth is determined by the configuration of the dye laser oscillator.
