KTP Crystal
KTP (KTiOPO4 ) ke e 'ngoe ea lisebelisoa tse sebelisoang ka ho fetisisa tse sa sebelisoeng tse sa bonahaleng tsa mahlo. Mohlala, e sebelisoa khafetsa bakeng sa ho pheta-pheta ha Nd: YAG lasers le li-laser tse ling tsa Nd-doped, haholoholo maemong a tlase kapa a mahareng. KTP e sebelisoa ka mokhoa o pharalletseng joaloka OPO, EOM, thepa ea tataiso ea maqhubu, le ho tataisa balekane.
KTP e bonts'a boleng bo phahameng ba 'mala, ponaletso e pharalletseng, kamohelo e kholo ea kamohelo, sekhutlo se tšesaane sa ho tsamaea, mme mofuta oa I le II o sa ts'oaneng le karo-karolelano ea phase-match (NCPM) maemong a pharalletseng. KTP e boetse e na le tšebetso ea SHG e sebetsang hantle haholo (makhetlo a 3 a phahameng ho feta a KDP) le likotsi tse tebileng tsa tšenyo ea mahlo (> 500 MW / cm²).
Li-kristale tsa KTP tse tloaetseng ho fetoloa ke flux li na le bothata ba ho fifala le ho sebetsa hantle ("grey-track") ha li sebelisoa nakong ea ts'ebetso ea SHG ea 1064 nm maemong a phahameng a matla le litekanyetso tsa ho pheta-pheta ka holimo ho 1 kHz. Bakeng sa lits'ebetso tse phahameng tsa matla a phahameng, WISOPTIC e fana ka litefiso tse phahameng tsa "grey track track" (HGTR) tsa KTP tse holisitsoeng ke mokhoa oa hydrothermal. Li-kristale tse joalo li na le ho kenngoa ka mokhoa oa IR ka tlase mme ha li angoe ke khanya e tala ho feta KTP e tloaelehileng, ka hona qoba mathata a ts'ebeliso ea matla a motlakase, marotholi a sebetsang hantle, ho fifala ha kristale le ho khopamisoa ha boroko.
Joaloka e mong oa bafani ba ka sehloohong ba mohloli oa KTP 'marakeng oa machabeng, WISOPTIC e na le bokhoni bo phahameng ba khetho ea thepa, ho e lokisa (polishing, coating), tlhahiso ea bongata, ho tlisa kapele le nako e telele ea tiiso ea boleng bo phahameng ba KTP. Ho boetse ho bohlokoa ho bolela hore theko ea rona e na le kahlolo e molemo haholo.
Ikopanye le rona bakeng sa tharollo e nepahetseng bakeng sa ts'ebeliso ea hau ea likristale tsa KTP.
