First Watt-Level Self Frequency Doubling (SFD) Laser at 540nm with Nd:LCB Crystal Utilizing Energy Level Splitting
A team of researchers have achieved a maximum of 1.7 W at 540nm using a self-frequency-doubling green laser in Nd3+-doped La2CaB10O19 (Nd:LCB) crystal by utilizing the energy level splitting of Nd3+ ions.
