We demonstrate two-dimensional spatial solitons excited by near-infrared picosecond pulses in Kerr-like heavy metal oxide glasses with a nonlinearity one order of magnitude larger than in fused silica. Solitons were obtained at 820 nm owing to the presence of multiphoton absorption, which prevented catastrophic collapse.
我们展示了在类克尔重金属氧化物玻璃中由近红外皮秒脉冲激发的二维空间孤子，其非线性比熔融石英大一个数量级。由于多光子吸收的存在，在820纳米处获得了孤子，这防止了灾难性的坍缩。
