The tuner bull illuminant and that operation method for the spectroscopic analysis which possesses stability output

摘要

Topic Solutions As for the laser system for the spectroscopic analysis catheter & the system making use of the obamodo cavity, the output fluctuation which occurs is decreased from the mode hopping in during wave length scanning. Regarding desirable execution form, using semiconductor profit medium, it decreases cost. Making use of the fiber pigtail, the laser cavity which possesses the dense cavity mode interval under 15GHz is formed. The diffraction grating is used as the tuning element. Alignment tolerance is decreased making use of the cylindrical lens, productivity improves.
