چکیده
Given its specific thermal characteristics, the sesquioxide crystal Lu(2)O(3) is a particularly promising laser host material. We demonstrate mode locking of a Yb:Lu(2)O(3) laser by use of a semiconductor saturable-absorber mirror. The laser emits up to 470 mW in the picosecond regime, corresponding to a pump efficiency as high as 32%. With dispersion compensation, pulses as short as 220 fs at an average power of 266 mW are obtained at 1033.5 nm. To our knowledge, this is the first demonstration of a femtosecond oscillator based on Yb:Lu(2)O(3).

Diode-pumped femtosecond passively mode-locked Yb:LPS laser
A diode-pumped passively mode-locked Yb:Lu2Si2O7 (Yb:LPS) laser is demonstrated for the first time, to our knowledge. Using a commercial semiconductor saturable absorber mirror (SESAM) as the mode locker and a pair of GiresTournois interferometer (GTI) mirrors for group-velocity dispersion (GVD) compensating, we have obtained stable femtosecond mode locked pulses. Two output couplers of transmi...

We present a semiconductor saturable absorber mirror mode-locked thin disk laser based on Yb:Lu(2)O(3) with an average power of 141 W and an optical-to-optical efficiency of more than 40%. The ideal soliton pulses have an FWHM duration of 738 fs, an energy of 2.4 microJ, and a corresponding peak power of 2.8 MW. The repetition rate was 60 MHz and the beam was close to the diffraction limit with...

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 کاملGeneration of 33-fs pulses from a passively mode-locked Cr(3+):LiSrAlF(6) laser.
Femtosecond and picosecond operating regimes of an argon-ion-pumped Cr(3+):LiSrAlF(6) laser, passively mode locked using a saturable absorber, are described. At low absorber concentrations, self-starting cw mode locking is demonstrated, which yields pulses as short as 33 fs after extracavity prism compensation. At higher concentrations, both cw mode-locked and Q-switched mode-locked operation i...
متن کامل1.8-THz-wide optical frequency comb emitted from monolithic passively mode-locked semiconductor quantum-well laser.
We report on an optical frequency comb with 14 nm (∼1.8 THz) spectral bandwidth at a -3 dB level that is generated using a passively mode-locked quantum-well laser in photonic integrated circuits fabricated through an InP generic photonic integration technology platform. This 21.5-GHz colliding-pulse mode-locked laser cavity is defined by on-chip reflectors incorporating intracavity phase mod...
