Spectroscopy and efficient laser action from diode pumping of a new broadly tunable crystal : Yb 3 1 : Sr 3 Y ( BO 3 ) 3
نویسندگان
چکیده
The first demonstration of laser action in a Yb 3ϩ :Sr 3 Y(BO 3) 3 crystal is reported. This new material exhibits particularly broad absorption and emission bandwidths (6 and 60 nm, respectively) and hence is of particular interest for diode-pumped femtosecond and tunable laser sources. Efficient operation from diode pumping (1.4 W of cw laser power obtained with 3.6 W of diode pump power and as much as 3.4 W of peak power from high-power quasi-cw pumping) together with smooth tunability (over 50 nm FWHM) is reported. For the comparison , efficiency and thermal limitations of Yb:glass and Yb:Ca 4 GdO(BO 3) 3 have been investigated under the same conditions.

Growth and Spectral Assessment of Yb3+-Doped KBaGd(MoO4)3 Crystal: A Candidate for Ultrashort Pulse and Tunable Lasers
In order to explore new more powerful ultrashort pulse laser and tunable laser for diode-pumping, this paper reports the growth and spectral assessment of Yb(3+)-doped KBaGd(MoO(4))(3) crystal. An Yb(3+):KBaGd(MoO(4))(3) crystal with dimensions of 50×40×9 mm(3) was grown by the TSSG method from the K(2)Mo(2)O(7) flux. The investigated spectral properties indicated that Yb(3+):KBaGd(MoO(4))(3) c...
متن کاملEfficient and tunable continuous-wave diode-pumped Yb3+:Ca4GdO(BO3)3 laser.
A Yb(3+):Ca(4)GdO(BO(3))(3) (Yb:GdCOB) crystal has been diode pumped for the first time to our knowledge. We obtained 47.5% slope efficiency at 6 degrees C, producing 191 mW of power at 1050 nm, with a 2.4% output coupler. Temperature does not significantly affect the laser performance: At room temperature we still obtained 180 mW of power for the same cavity. We achieved tunability of the Yb:G...

Efficient cw self-frequency-doubled green laser output of 160 mW has been obtained from Yb:YAl(3)(BO(3))(4) crystal pumped by 1.4-W incident power from a fiber-coupled 976-nm laser diode. The incident-pump-power-green-output-power conversion efficiency is greater than 11.3%, and the electrical-input-green conversion efficiency is 3.9%. Tunable green output from 513.0 to 545.8 nm is also demonst...
متن کاملContinuous-wave and femtosecond laser operation of Yb:CaGdAlO4 under high-power diode pumping.
We demonstrate the generation of 68 fs secant hyperbolic pulses at a 105 MHz repetition rate with an average power of 520 mW from a diode-pumped Yb(3+):CaGdAlO(4) mode-locked laser. A semiconductor saturable absorber allows passive mode locking, and a 15 W diode laser is used to pump directly the crystal. To our knowledge this represents the highest average power ever obtained for a sub-100 fs ...
متن کاملHigh power diode pumped Yb 3 + : CaGdAlO 4 laser
Yb:CaGdAlO4 [1] has been recently demonstrated to be very interesting for the development of next generation diode–pumped short-pulsed modelocked lasers. In fact, this crystal demonstrated two very promising properties. First, it has, to our best knowledge, the broadest and the flattest emission band of the Yb:doped materials. This allowed the generation of 47 fs pulses at a low average power o...
