Parutan dua dimensi bahan polimer hibrid yand dicampur dengan dai-laser organik telah difabrkasi. Prekursor polimer hibrid disintesis daripada monomer TMSPMA dengan kaedah sol-gel. Prekursor polimer hibrid ditambah dengan fotopemula sehingga menjadi sensitif terhadap cahaya ultraviolet.Filem polimer hibrid yang fotosensitif telah disinari dengan pembelauan laser THG Nd-YAG (λ=355nm),menghasilkan parutan dua dimensi dengan struktur heksagonal. Ciri laser dikaji dengan menggunakan garis strip pengujaan cahaya laser SHG Nd-YAG (λ=532nm). Panjang gelombang laser dicerap pada 606 dan 621 nm untuk kala parutan masing-masing pada 400 dan 410 nm. Lebar spektrum (FWHM) laser adalah sekitar 3 nm untuk daya pam 14,88 mJ/denyut cm2.
A two dimensional grating has been fabricated from hybrid polymer incorporated with organic dye-laser. The precursor hybrid polymers were synthesized from TMSPMA by sol-gel method. The precursor was mixed with photo-initiator to make sensitive with UV light. The photosensitive film was irradiated by laser interference of THG Nd-YAG laser (λ= 355 nm) yield 2D grating with hexagonal structure. The characteristic of lasing was investigated using strip-line excitation light of SHG Nd-YAG laser (λ = 532 nm). The lasing wavelengths are observed at 606 and 621 nm for grating period of 400 and 410 nm, respectively. The spectral width (FWHM) of lasing is about 3 nm at pumping power 14.88 mJ/pulse cm2.
