H. Belaidi et al., STABILITY TRANSFER OF STABILIZED AR-2 LASER TOWARDS A FREQUENCY STANDARD AROUND 1.3 MU-M( LASER ON OPTICALLY PUMPED I), IEEE transactions on instrumentation and measurement, 44(2), 1995, pp. 461-463
A Doppler-free stimulated-emission technique using an optically pumped
It laser with applications in spectroscopy and infrared frequency sta
ndards is reported. A single mode CW Argon ion laser, locked on a hype
rfine component of the 13P(43-0) line of the B-X electronic transition
(127)I2 iodine molecule, is used as laser pump. Continuous wave oscil
lation is observed on transitions belonging to the B-X system into hig
hly excited vibrational levels of the ground state. The long term stab
ility of the Argon laser (Delta nu/nu approximate to 10(-13) in 100 s)
can be transferred to the iodine laser.
