Ukusetshenziswa kwe-Neodymium Ion Concentration Gradient YAG Crystal ku-End-Pumped Laser Technology

Ukuthuthukiswa okusheshayo kobuchwepheshe be-laser akunakuhlukaniswa kusukela ekuthuthukisweni okukhulu kwama-lasemiconductor lasers, izinto zekristalu yokwenziwa kanye namadivayisi. Njengamanje, umkhakha we-semiconductor kanye ne-solid state laser technology uyachuma. Ukuze siqhubeke siqonde isimo socwaningo lwesayensi esisezingeni eliphezulu kanye nezidingo zesicelo sokuvikela sokuvikela kuzwelonke ze-semiconductor yamandla aphezulu kanye nobuchwepheshe be-laser bombuso oqinile, futhi kugqugquzelwe ukuhwebelana kwezemfundo enhla naphansi kobuchwepheshe be-laser, i-Chinese Society of Optical Engineering izobamba. i-“Advanced Semiconductor, Solid-State Laser Technology and Application Exchange Conference” ngo-2024 ukuze kwenziwe ukuhwebelana okujulile ngezimiso eziphathekayo, ubuchwepheshe obubalulekile, ukuqhubeka kwesicelo, namathemba esikhathi esizayo ahlobene nama-semiconductors nama-solid-state lasers.

Kulo mhlangano, usihlalo wenkampani yethu, uZhang Jianjun, ubike ngokusetshenziswa kwei-neodymium ion concentrationi-gradientIkristalu ye-YAGkubuchwepheshe be-laser bokugcina.Ama-laser-state Solid ngokuvamile ampontshwa ngokubona, futhi kunezinhlobo ezimbili eziyinhloko zezindlela zokumpompa: iphampu yesibani nepompo ye-diode. Amalaser e-Diode-pumped solid-state (DPSSL) anezinzuzo zokusebenza kahle okuphezulu, ikhwalithi ephezulu yothango, ukuzinza okuhle, ukwakheka okuhlangene, nempilo ende. I-Diode pumping isetshenziswa kuma-laser we-Nd:YAG ngezindlela ezimbili zokumpompa: ukumpompa eceleni (okubizwa ngokuthi ukumpompa eceleni) kanye nokuqeda ukumpompa (okubizwa ngokuthi ukumpompa kokuphela).

Uma kuqhathaniswa nokumpompa isibani kanye nokumpompa ohlangothini lwe-semiconductor, ukumpompa kokugcina kwe-semiconductor kulula ukufeza ukufanisa imodi phakathi kokukhanya kokumpompa nokukhanya okuzungezayo emgodini we-laser. Ngaphezu kwalokho, ukugxilisa isigxobo sephampu kusayizi omncane kancane kunenduku ye-laser kungakhawulela inani lamamodi endaweni futhi kuthuthukise ngempumelelo ikhwalithi ye-beam. Ngesikhathi esifanayo, inezinzuzo zesakhiwo esihlangene, umkhawulo we-laser ophansi, nokusebenza kahle okuphezulu. Ucwaningo luye lwabonisa ukuthi ukumpompa ukuphela okwamanje kuyindlela ephumelela kakhulu yokumpompa.
