摘要:In this paper we present a passively mode-locked laser oscillator based on Yb:LPS crystal with a single-mode laser diode as a pumping source. The pulsed operation was initiated with a semiconductor saturable absorber mirror. The pulses were as short as 90 fs, which, to the best o...

摘要:Tube bending locally heated by a laser beam is analysed. This heating reduces the yield stress and prevents stress hardening thus making easier the process of plastic deformation. In the present work simple model of elasto-plastic bending of circular tubes is developed and some e...
