abstract: We have demonstrated the stable mode locked Nd:GdVO4 laser operating on the F 4(3/2) I 4(9/2) transition at 912 nm. With a four mirror folded cavity and a semiconductor saturable absorber mirror for passive mode locking, we have gained 6.5 ps laser pulses at a repetition rate of 178 MHz. The laser is diode end pumped, and the total output Power from the out coupler is 128 mw at an incident pump power of 19.7 W. (C) 2008 Elsevier B.V. All rights reserved.

abstract: Abstract A high power diode end pumped passively Q switched and mode locking (QML) Nd:GdVO4 laser at 912 nm was demonstrated for the first time, to the best of our knowledge. A Z type laser cavity with Cr4+:YAG crystals as the intracavity saturable absorber were employed in the experiments. Influence of the initial transmission (TU) of the saturable absorber on the QML laser performance was investigated. Using the TU 95% Cr4+:YAG, as much as an average output power of 2.0 W pulsed 912 nm laser was produced at an absorbed pump power of 25.0 W, then the repetition rates of the Q switched envelope and the mode locking pulse were 224 kHz and 160 MHz, respectively. Whereas the maximum output power was reduced to 1.3 W using the TU 90% Cr4+:YAG, we obtained a 100% modulation depth for the mode locking pulses inside the Q switched envelope.

abstract: We have demonstrated a passively mode locked diode end pumped all solid state laser, which is composed of a Nd:Gd0.5Y0.5VO4 crystal and a folded cavity with a semiconductor saturable absorber mirror grown by metal organic chemical vapor deposition. Stable cw mode locking with a 3.8 ps pulse duration at a repetition rate of 112 MHz was obtained. At 13.6 W of the incident pump power, a clean mode locked fundamental mode average output power of 3.9 W was achieved with an overall optical to optical efficiency of 29.0% and the slope efficiency was 38.1%

abstract: Passive mode locking of a Nd:KGW laser with hot band diode pumping at 910 nm was demonstrated. A semiconductor saturable absorber mirror was used as a mode locking mechanism. The laser generated 2.4 ps pulses at a repetition rate of ~83.8 MHz. An average output power of 87 mW was obtained at 1067 nm. To the best of our knowledge, this is the first report on passive mode locking of a Nd:KGW laser with low quantum defect pumping which holds great promise for further output power scaling.

abstract: Mode locking technique is a widely used method for generating ultrashort laser pulses. The mode locked laser output is a sequence of equally spaced laser pulses. The pulse width is limited by the spectral range of the gain medium and inversely related to the bandwidth of the laser emission. Compared with the active mode locking technique, passively modelocked laser with saturable absorber is able to generate much shorter pulse with a simple configuration. In particularly, based on the passive mode locking mechanism, the Kerr lens mode locking (KLM) Ti:sapphire laser is recognized as the most important ultrafast laser source. Not only a series of commercial femtosecond lasers with Ti:sapphire crystal were released, but also lead to many innovations in science, such as frequency comb, laser wake field acceleration, attosecond science, laser micro fabrication etc. However, the major drawback of Ti:sapphire laser is its green pump laser source. Currently available green lasers generated by frequency doubled Nd:YAG laser or by Argon laser are relatively bulky and expensive, which limits the practical application of ultrafast Ti:sapphire lasers.
