We experimentally investigate lag synchronization in mutually coupled Nd:YAG lasers. Two laser diode pumped Nd:YAG lasers, when they are electronically coupled, exhibit lag synchronization for a strong coupling strength region. We investigate the synchronous behaviors of the lasers by analyzing error dynamics, phase portraits, and similarity function. We confirm the observation of lag synchronization by obtaining the probability distribution of the intermittent lag synchronization length before lag synchronization.
