Isi ihe dị n'ime laser ọ bụla bụ ihe na-arụ ọrụ laser, yana ihe na-arụ ọrụ nke steeti siri ike.laserọ siri ike n'ezie. Ọtụtụ ihe eji emegharị laser siri ike nwere matrices kristal na atọm ma ọ bụ ion nwere ọrụ laser, ebe matrices amorphous (iko) adịghị ahụkebe. A na-atụ anya na mmepe kachasị ọhụrụ na teknụzụ nkwadebe seramiiki ga-agbasa nke ukwuu oke ojiji nke ihe laser dị ọnụ ala na nke dị elu, nke enwere ike ime n'ogo buru ibu karịa nke ihe kristal.

Ihe laser siri ike a na-ejikarị eme ihe bụ isi

Ruby: Ihe mejupụtara kemịkalụ ya bụ chromium-doped aluminum oxide (Cr:Al₂O₃). Ruby e kere eke nwere ihe mejupụtara kemịkalụ yiri nke ruby ​​dị mma, mana ha dị ọcha ma dịkwa mma karịa. Ha na-acha pink ma nwee ogologo laser nke 694.3 nanomita.

2. yttrium aluminum garnet nke Neodymium doped (Nd:YAG): Kristal arụrụ arụ, nke nwere ogologo laser nke nanomita 1064, ọ bụ nke ìhè infrared dị nso ma ọ bụ nke a na-anaghị ahụ anya ma dịkwa ize ndụ maka anya. Nd:YAG bụ ihe laser siri ike nke a na-ejikarị eme ihe ugbu a, nke karịrị ruby. Isi ihe kpatara ya bụ na oke laser ya dị ala, ọ nwekwara ike nweta ike mmepụta dị elu n'okpuru otu ike ntinye.

3. yttrium vanadate nke Neodymium-doped (Nd:YVO₄) A na-akpọkarị ya "vanadate", ọ ghọwo ihe a na-ahọrọ maka lasers siri ike nke diode-pumped dị ala ruo nke etiti (ruo ọtụtụ watts) n'ihi nnukwu akụkụ ya nke e tinyere n'ime mmiri ọkụ, obere oghere laser na njirimara mmepụta polarized. Ogologo ebili mmiri ọrụ bụ nanomita 1064 na nanomita 1340, mgbe ugboro ugboro abụọ gasịrị, ọ nwere ike iwepụta lasers nwere ogologo ebili mmiri nke nanomita 532 na nanomita 670.

4. Iko Neodymium-doped (Nd:Glass): Site na iji iko amorphous dị ka matrix, njirimara laser ya yiri nke Nd:YAG. Isi ihe ọghọm ya bụ na ike okpomọkụ ya dị obere, naanị 1/10 nke kristal, na-eme ka ọ sie ike ịjụ oyi na ngwa ike dị elu. Agbanyeghị, uru ya dị na eziokwu ahụ bụ na enwere ike ime ya ka ọ bụrụ ihe mgbasa ozi laser nke nwere dayameta karịrị otu ụkwụ, na-achịkwa njupụta ike nke ọma, na-ezere mmebi nke ihe anya na ọkwa kilojoule.laser pulsed, na inwe ọnụ ahịa dị ala.

Ihe ndị ọzọ dị mkpa e ji laser siri ike mee, ihe ndị e ji erbium mee: gụnyere erbium-doped yttrium aluminum garnet (Er:YAG, output wavelength 2940 nanometers) na erbium-doped Glass (Er:Glass, output wavelength 1540 nanometers). Ihe ndị e ji holmium mee: gụnyere holmium doped yttrium aluminum garnet (Ho:YAG), holmium doped lithium yttrium fluoride (Ho:YLF), na holmium doped Glass (Ho:glass, output wavelength 2000 ruo 2100 nanometers). Ihe ndị e ji thulium mee: gụnyere thulium-doped yttrium aluminum garnet (Tm:YAG), thulium-doped lutetium aluminum garnet (Tm:LuAG), na thulium-holmium co-doped lithium yttrium fluoride (Tm,Ho:YLF, output wavelength 2000 ruo 2030 nanometers). Ihe ndị e ji Ytterbium mee: dịka ytterbium-doped potassium gadolinium tungstate (Yb:KGW, ebili mmiri mmepụta 1025 ruo 1045 nanomita). Alexandrite (ebili mmiri mmepụta 655 ruo 815 nanomita). Sapphire nke titanium mee (Ti:Sapphire, ebili mmiri mmepụta 840 ruo 1100 nanomita)
