چکیده

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%.

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.

IN-BAND PUMPING OF Nd-BASED SOLID-STATE LASERS

The author is presenting output performances obtained from Nd-based laser materials that were in-band pumped directly into the F3/2 emitting level. Continuous-wave (cw) laser operation at 1.06 μm with slope efficiency of 0.79 in Nd:YAG and 0.80 in Nd:GdVO4 and Nd:YVO4 was realized using an end-pumping configuration and a tunable Ti:Sapphire laser around 0.88 μm as source of excitation. These sl...

Spectroscopic properties and laser performance of resonantly-pumped cryo-cooled Er³⁺:GdVO₄.

We report a highly efficient cryo-cooled eye-safe laser operation of a resonantly-pumped (in-band) Er³⁺:GdVO₄ single crystal. The maximum continuous wave (CW) power of 10.3 W with 84% slope efficiency was achieved at 1598.7 with pumping at 1538.6 nm by a spectrally-narrowed Er-fiber laser. Under the 1529 nm resonant pumping by a commercially available diode bar stack operating in a quasi-CW (QC...

High-power diode-end-pumped passively mode-locked Nd:YVO4 laser with a relaxed saturable Bragg reflector

We present an efficient diode-end-pumped passively mode-locked Nd:YVO4 laser with a relaxed single-quantum-well saturable Bragg reflector (SBR), which average output power is more than 23 W and pulse duration 2 1 .5 ps cw modelocking is generated corresponding to 50 W pumping power. The overall optical-optical efficiency reaches 47% and to our knowledge, this is the highest conversion efficienc...

Femtosecond Cr:Colquiriite Lasers Pumped by a Single Tapered Diode Laser

Ti:Sapphire lasers could provide tunable femtosecond pulses in the 680-1180 nm region; however, due to the requirement of expensive green pump sources, its current cost sets a barrier to its widespread adoption. As an alternative, Cr :Colquiriites (Cr:LiCAF, Cr:LiSAF, Cr:LiSGaF) also possess broad gain bandwidths and their total cw tuning range cover the 720-1110 nm region. Moreover, their broa...
