Abstract：

The　layered　van　der　Waals　materials　γ-InSe　showed　great　potential　in　integrated　photonic　devices　and　microlasers　due　to　the　high　electron　mobility,　wide　tunable　direct　bandgap,　and　high　lattice　compressibility.　However,　γ-InSe　crystal　has　weak　stability　and　dissociation　tendency　in　ambient　conditions,　which　hampers　its　applications.　Herein,　we　proposed　a　novel　method　for　single-crystal　InSe.　By　thermal　stretching　combined　with　photothermal　processing,　ultralong　and　layered　single-crystal　InSe　fibers　were　obtained.　The　InSe　fiber　core　was　effectively　restrained　and　protected,　improving　the　mechanical　properties　and　stability　of　the　device.　Moreover,　by　using　a　532　nm　nanosecond　pulse　laser　as　the　pump　source,　the　WGM　microlaser　operating　at　1107.33　nm　was　obtained.　This　work　provides　a　convenient　approach　for　van　der　Waals　materials　preparation　and　paves　the　pathways　for　the　development　of　light　sources　for　layered　van　der　Waals　materials.　©　COPYRIGHT　SPIE.
