We have demonstrated continuous wave (CW) laser operation and the first, to the best of our knowledge, sub-200 fs mode-locked laser operation of Nd(3+)-doped Ba(Zr,Mg,Ta)O(3) ceramic. Its disordered crystalline nature exhibits a broad gain bandwidth of 30 nm with a high-emission cross section. It also has higher thermal and mechanical properties than Nd:glass. In CW operation, a maximum output power of 1.5 W under 6.2 W of absorbed pump power was obtained. In mode-locked operation, a pulse duration of 196 fs with an average power of 60 mW was successfully achieved. The laser spectrum straddled both fluorescence peaks of A-site and B-site Nd(3+) ions.

Transparent dielectric ceramics were developed originating from dielectric ceramics of which development was conducted by Dr. Wakino for microwave applications. A Ba(Mg, Ta)O3 based transparent ceramics shows high transparency and various optical properties depending on the composition. Based on the knowledge obtained from the study of Ba(Mg, Ta)O3 based transparent ceramics, we also developed other transparent ceramics such as LaAlO3-Sr(Al, Ta)O3 solid solution. The Ba(Mg, Ta)O3 based transparent ceramics was commercially utilized as high-refractive-index lens for slim digital camera applications, where the refractive indices reduced the focal length of optical lens modules.

We report efficient CW laser operation and first femtosecond mode-locked laser operation of transparent Nd3+:Ba(Zr,Mg,Ta)O3 ceramic. The disordered crystalline system exhibits the characteristic broadband absorption and fluorescence spectra suitable for ultrashort pulse lasers.

Nd<sup>3+</sup>-doped Ba(Zr,Mg,Ta)O<inf>3</inf> ceramic laser is reported. The broadband fluorescence profile can be tailored by the “disordered” perovskite structure and is suitable for ultrashort pulse lasers. Mode-locked laser operation was demonstrated for the first time.
