Nd:YVO4
Nd:YVO4 crystal ndeimwe yeanonyanya kushanda laser host crystal iripo ye diode laser pumped solid state lasers. Yayo yakakura yakasimudzwa emission cross-section pa lasing wavelength, high absorption coefficient uye yakafara absorption bandwidth papombi wavelength, yakakwira laser induced kukuvara chikumbaridzo pamwe nekunaka kwemuviri, optical uye michina zvivakwa zvinoita Nd: YVO4 yakanakisa kristaro yesimba repamusoro, yakagadzikana uye inodhura inoshanda diode pumped solid-state lasers.
Features uye Applications
★ Low lasing chikumbaridzo uye yakakwirira materu kushanda
★ Kudzikira kutsamira pane pombi wavelength
★ Yakakura inokurudzirwa emission muchinjiko-chikamu pa lasing wavelength
★ Kunyura kwepamusoro pamusoro pekupomba kwakafara kwewavelength bandwidth
★ Optically uniaxial uye hombe birefringence inoburitsa polarized laser
★ YeIngle-longitudinal-mode kubuda uye compact dhizaini
★ Diode laser-pumped Nd:YVO4 compact laser uye yayo frequency-yakapetwa kaviri girini, tsvuku kana bhuruu laser ichave yakakodzera laser maturusi ekugadzira, kugadzira zvinhu, spectroscopy, wafer inspection, light show, medical diagnostics, laser printing uye zvimwe zvakapararira. applications
