โœฆ Synopsis

An one-end-pumped Nd:YVO~4~ laser with fiber- coupled diode is designed. The mode matching between pump mode and laser mode is analyzed, and the optimum mode matching coefficient is obtained by optimizing the pump mode. Based on the optimal pump mode, a 14.2W TEM~00~ mode CW laser is obtained with a optical-optical efficiency of 55.7% at 1064 nm, with M

We report on an 880 nm LD pumped passive modelocked TEM00 Nd:YVO4 laser based on a semiconductor saturable absorber mirror (SESAM) for the first time. When the incident pump power was 16 W, 4.76 W average output power of continuous-wave mode-locked laser with an optical-to-optical conversion efficie

In this paper, we demonstrate a high-power erbiumdoped fiber amplifier pumped by single-mode titanium sapphire (Ti:S) laser at 980 nm. The highest output power of 22.6 dBm is measured at 1549 nm with an input signal power of 4 dBm and a pump power of 300 mW. This corresponds to power-conversion effi
