A new ring-based tunable laser on a chip emits multiple wavelengths smoothly, offering a compact, cost-effective alternative ...

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 ...
