Relation between ambient temperature and the output power of optical-contact crystal green lasers

In this paper, from detailed experiment-based research on how ambient temperature influences the output power of optical-contact crystal green laser, it is showed that the output power of optical-contact crystal laser is directly affected by ambient temperature, and individual difference exists in the optical-contact crystals. The negative effect caused by low ambient temperature can be eliminated by temperature control sleeves. Most optical-contact crystal lasers work well at room temperature.
