Narrow-band linearly scannable infrared lasing between 1.09 and 1.12 microm in the dye DNDTPC perchlorate.
A grazing-incidence grating-tuned oscillator followed by two amplifier stages has been used to generate 0.2-cm(-1) bandwidth scannable infrared radiation between 1.09 and 1.12 microm. When the radiation was pumped with 400-mJ 10-nsec pulses from a Nd:YAG laser, the output-pulse energy was approximately 20 mJ at the peak of the tuning curve.
