ABSTRACT
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.
Keywords: 2D-grating;
hexagonal structure; hybrid polymer; laser
ABSTRAK
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 foto-pemula sehingga
menjadi sensitif terhadap cahaya ultraviolet. Filem polimer hibrid yang
fotosensitif telah disinari dengan pembelauan laser THG Nd-YAG
(λ = 355 nm), menghasilkan parutan dua dimensi dengan struktur heksagonal.
Ciri laser dikaji dengan menggunakan garis strip pengujaan cahaya laser SHG Nd-YAG
(λ = 532 nm). 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.
Kata kunci: laser;
parutan dua dimensi; polimer hibrid; struktur heksagonal
