Summary from only given. We present a simple passively modelocked diode-pumped Yb:KGd(WO/sub 4/)/sub 2/ (Yb:KGW) laser. We achieved pulses as short as 150 fs and an average output power of 1.5 W by ...

A recognized drawback of edge-emitting diode lasers is their high divergence and elliptical beam shape since the first diode laser was demonstrated. In this paper, we demonstrated the ultranarrow ...
