Diode-pumped passively mode-locked Nd:YVO4 laser at 914 nm.
We demonstrate, for the first time, to our knowledge, a diode-pumped passively mode-locked Nd:YVO4 laser, operating on the 4F(3/2)-4I(9/2) transition of the neodymium ion at 914 nm. We obtained 8.8 ps pulses at approximately 914 nm at a repetition rate of 94 MHz, and an averaged output power of 87 mW by using a semiconductor saturable absorber mirror.
متن کاملHighly efficient Nd:YVO4 laser by direct in-band diode pumping at 914 nm.
A Nd:YVO4 crystal was pumped directly into the emitting level by a laser diode at 914 nm for the first time to our knowledge. We achieved an output power of 11.5 W at 1064 nm for an absorbed pump power of 14.6 W, corresponding to an optical efficiency of 78.7%. We demonstrated that thermal effects are very weak, in agreement with the low quantum defect of only 14.1%.
متن کامل1064 nm Nd:YVO4 laser intracavity pumped at 912 nm and sum-frequency mixing for an emission at 491 nm.
We present for the first time a Nd:YVO(4) laser emitting at 1064 nm intracavity pumped at 912 nm by a Nd:GdVO(4) laser. We carried out a model to design the system properly, and laser performance was experimentally investigated. Intracavity sum-frequency mixing at 912 and 1064 nm was then realized in a BiBO crystal to reach the blue range. We obtained a cw output power of 155 mW at 491 nm with ...
متن کاملDiode-pumped Nd:YAG laser emitting at 899 nm and below.
We present what is, to the best of our knowledge, the first diode-pumped Nd:YAG laser emitting at 899 nm and below, based on the (4)F(3/2) - (4)I(9/2) transition, generally used for a 946 nm emission. A power of 630 mW at 899 nm has been achieved in cw operation and 16 mW at 884 nm with a fiber-coupled laser diode emitting 9 W at 808 nm. Intracavity second-harmonic generation in cw mode has als...
متن کاملOptimization of a 2.3 μm Yb:Tm:YLF laser, pumped at 685 nm and 960 nm simultaneously
For the first time, a unique pumping scheme for the thulium 2.3 micrometer transition is proposed that is capable of enhancing the output power by almost a factor three when compared to the traditional pumping scheme at 960 nm. The best relation between 685 nm pump power and 960 nm pump power is shown. The achieved output power of 620 mW is the highest reported so far. Introduction Tunable lase...
