Abstract

A first international comparison of I/sub 2/-stabilized Nd:YAG lasers has been made between National Research Laboratory of Metrology (NRLM, Japan) and Joint Institute for Laboratory Astrophysics (JILA, USA). The results of the comparison show that the Allan variance of the portable NRLM laser has reached <3/spl times/10/sup -13/ when the integration time is larger than 100 s. Frequency difference between the NRLM laser and the JILA laser is 3563 Hz (of IR light) with the matrix-averaged standard deviation of about 310 Hz.
