Low loss, optical channel waveguides have been successfully produced by high repetition rate femtosecond laser inscription in a Li–Zn fluoroborate glass (64.9B 2 O 3  + 25Li 2 O + 10ZnF 2  + 0.1Er 2 O 3 ). High quality waveguides were produced at 500 kHz, 1 MHz and 2 MHz laser repetition rates, show...
