One of the common high power pulsed lasers are based on a Nd-doped laser, but the pulses are not short of femtosecond region. Recently, the development of a new ceramic laser medium has been reported. The Nd$$^{3+}$$: (GSAG$$_{0.67}$$: YSGG $$_{0.33}$$) has a significantly broader spectral bandwidth (5 nm) and four times higher thermal conductivity than Nd-doped glass materials. And the ceramic materials have a potential for a high power laser system because they have a size scalability and stronger fracture toughness than single crystal. In this presentation, we successfully demonstrated for the first time a diode-pumped mode-locked Nd$$^{3+}$$: (GSAG$$_{0.67}$$: YSGG $$_{0.33}$$) ceramic laser. We believe that further optimizing the resonator design enable generation of femtosecond pulses by using Kerr-lens mode locking and this ceramic material has a potential as amplified laser medium for diode-pumped subpicosecond systems at high repetition rates.

One of the common high power pulsed lasers are based on a Nd-doped laser, but the pulses are not short of femtosecond region. Recently, the development of a new ceramic laser medium has been reported, namely the Nd-doped mixed scandium garnets Nd$$^{3+}$$:(GSAG$$_{0.67}$$:YSGG$$_{0.33}$$). The Nd$$^{3+}$$: (GSAG$$_{0.67}$$:YSGG$$_{0.33}$$) has a significantly broader spectral bandwidth (5 nm) and four times higher thermal conductivity than Nd-doped glass materials. And the ceramics have a potential for a high power laser system because they have a size scalability and stronger fracture toughness than single crystal. We successfully demonstrated for the first time a mode-locked Nd$$^{3+}$$-doped mixed scandium garnets (Nd$$^{3+}$$:(GSAG$$_{0.67}$$:YSGG$$_{0.33}$$)) ceramic laser.
