摘要

提出一种热压法制备微盘激光器的工艺, 仅使用实验室常用电阻加热炉具即可制备出不同直径/厚度的微盘激光器. 选用TeO₂-ZnO-Na₂O碲酸盐玻璃为基质材料, 制备出直径分布在100—400 μm范围内、最小厚度可达8 μm、典型品质因数(Q值)约为10⁵的微盘激光器. 对碲酸盐玻璃基质材料掺入稀土离子Nd³⁺和Tm³⁺, 通过光纤锥耦合法开展微盘的抽运耦合实验, 即可在耦合系统的输出光谱中获得明显的荧光回廊模式和激光模式. 以一颗直径为105.74 μm、厚度为10.4 μm的Nd³⁺掺杂微盘为例, 当抽运光功率提升至1.364 mW以上时, 即可在1.06 μm附近获得激光峰. 同样实验表明, 对Tm³⁺掺杂的微盘进行抽运耦合实验可获得1.9 μm附近的激光峰.

Abstract

In this work, we report a two-step thermal pressing method of fabricating microdisk lasers that are suitable for processing thermally stable glass materials, and we utilize a tellurite glass (TeO₂-ZnO-Na₂O) to demonstrate the feasibility of this method. Compared with the conventional microdisk fabricating methods that rely on a series of complicated procedures, such as lithography, etching, thermal reflow, and ion implantation, this thermal pressing method involves only two heating procedures and can be accomplished with simple laboratory resistive heating furnaces. In the first heating procedure, we crush bulk tellurite glass into powders and drop those powders through a vertical heating furnace. Glass powders are transformed into microspheres by surface tension in the furnace. In the second heating procedure, microspheres are placed between two flat/smooth surfaces and are thermally treated when being pressed with suitable weights. With this procedure, the “flattened” microspheres turn into the microdisks. In this work, we demonstrate that our fabricated tellurite glass microdisks possess diameters of 100－400 μm, thinnest thickness of ～ 8 μm, and typical quality-factor (Q-factor) of ～ 10⁵. We also dope tellurite glass with active dopants such as Nd³⁺ and Tm³⁺ to fabricate the active microdisk resonators. We couple those active microdisk resonators with fiber tapers and demonstrate that with appropriate pump power, apparent fluorescence whispering gallery mode and laser mode can be obtained. Taking a 105.74-μm-diameter, 10.4-μm-thickness, and Nd³⁺-doped tellurite glass microdisk for example, we show that as the pump power increases above a threshold of 1.364 mW, a lasing peak near 1.06 μm can be obtained. We also show that lasing peaks near 1.9 μm can be obtained by coupling/pumping Tm³⁺ doped microdisks.
