Diamond se yon chwa ideyal pou aparèy optoelectronic nan anviwònman ekstrèm akòz ultra-segondè konduktiviti tèmik li yo, gwo-spectre transmisyon, ak ekselan estabilite fizikochimik . an menm tan an, dyaman tou posede pwopriyete Raman ekselan, tankou pi gwo chanjman nan men ou. CM/GW) nan mitan kristal yo li te ye, ki fè li yon mwayen genyen ideyal pou agrandi longèdonn lazè ak ogmante pouvwa a pwodiksyon lazè .
The research team overcame the key technologies of large-size, low-stress diamond single crystal preparation and low roughness, high parallelism diamond crystal processing, and developed a diamond Raman laser crystal with excellent optical properties. Based on the diamond laser crystals, the team has successfully developed an eye-safe diamond Raman laser with<1 ns pulse width, MW peak power, and kHz high frequency reproduction. This achievement marks the team's significant progress in high-quality diamond laser crystal materials and Raman laser technology.
Gwo-gwosè dyaman Raman kristal endepandamman grandi nan ekip la
By constructing a V-shaped folded cavity and a short Raman cavity structure, the team utilized the Raman-induced cavity inversion effect to realize the rapid release of laser energy, and ultimately obtained a 1.45 µm human-eye-safe-band diamond Raman laser with a pulse width of only 0.6 ns and a peak power of up to 913.3 kW, ki mete yon nouvo dosye sou pèfòmans pou menm kalite aparèy nan tèren entènasyonal la. Anplis de sa, lazè a montre yon frekans repetisyon segondè (1-10 kHz) ak bon jan kalite gwo bout bwa (m² <1.5), ki ka satisfè kondisyon yo aplikasyon nan alontèm ak senaryo deteksyon-wo presizyon tankou satelit sòti.
Diamond Raman lazè konfigirasyon eksperimantal (agòch) ak karakteristik pwodiksyon (adwat)
Lokalizasyon nan gwo-gwosè ak-wo kalite dyaman lazè kristal pral siyifikativman diminye pri a manifakti nan aparèy lazè Raman ak enjekte yon UN fò pou devlopman nan endistri ki gen rapò . Lachin .
