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 ...

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 ...
