ABSTRACT
A series of experimental studies on the emission spectra of laser-induced plasma at reduced ambient gas pressure were carried out for the analyses of organic materials. The plasma was generated by means of a Q-switch Nd-YAG laser having a pulse width of 8 ns, wavelength of 1,064 nm and operated...

Au-Ag nanoalloys disintesis dengan menggunakan tehnik laser radiasi femtosecond dengan metode top-down maupun bottom-up. Metode top-down Au-Ag nanoalloys disintesis dari pelat Au dan Ag sedangkan metode bottom-up disintesis dari garam metal silver nitrate AgNO3 dan garam metal emas Potassium gold III chloride K AuCl4 . Pada metode top-down, pelat Au...

ABSTRAK
Pada proses engraving penggunaan laser berdaya tinggi marak digunakan saat ini. Laser daya tinggi yang sering digunakan adalah laser gas seperti CO2, Nd:YaG dan laser diode. Laser diode memiliki beberapa kekurangan diantaranya sudut divergensi lebar, astigmatisme dan beam profile yang tidak ideal yang berbentuk elips. Kekurangan tersebut menyebabkan kualitas beam...
