Nuclear-Pumped Lasers - NASA Technical Reports Server
Le système intègre une photodiode Silicium à l'arrière du miroir de sortie, ainsi qu'une lentille de focalisation à l'entrée (cf. TP He-Ne 1A).
1 Principles of LasersWe describe an oblique incidence optical transmittance difference technique for determining the pointing stability of a laser. In this technique, we follow ... Photonique Expérimentale Laser - LEnsEMoreover, the transverse RFD provides in He-Ne lasers more uniform distribution of the gain and increases the gain of the laser active medium. The optimum pres-. Laser pointing stability measured by an oblique-incidence optical ...Calibration: For calibration we use a He-Ne-laser because its wavelength (?=632,8 nm) is well known and its spectral width is very low (? 10?3 nm). Adjust the ...
