Selective laser melting (SLM) has established itself as the most prominent additive manufacturing (AM) process for metallic structures in aerospace, automotive and medical industries. For a reliable employment of this process, it has to conform to the demanding requirements of these industries in terms of quasistatic and, especially, fatigue performance. Shafaqat Siddique identifies the influen…
Femtosecond lasers opened up new avenue in materials processing due to its unique features of ultrashort pulse width and extremely high peak intensity. One of the most important features of femtosecond laser processing is that strong absorption can be induced even by materials which are transparent to the femtosecond laser beam due to nonlinear multiphoton absorption. The multiphoton absorption…
Bangka Island is blessed with abundant tin mineral wealth. This is because the position of Bangka Island is inseparable from its geological setting which is the final phase of the Southeast Asian Tin Belt route (Cobbing, 1992 in Setiadji, 2014) which stretches from Thailand, Myanmar, Malaysia, Riau Islands, and Bangka Island. This research is located in Trubus area, Central Bangka, Kep. Bangka …

Telah dilakukan pembangkitan tunable gelombang mikro dengan Fiber Bragg Grating menggunakan sumber cahaya berupa laser dioda. Pembangkitan ini dilakukan dengan mencampurkan dua buah cahaya berbeda panjang gelombang hasil refleksi FBG sehingga menghasilkan suatu beat signal hasil interferensi konstruktif dengan nilai frekuensi yang berada pada rentang gelombang mikro. Hasil eksperimen menun…
