High-power laser with Nd:YAG single-crystal fiber grown by the micro-pulling-down technique.
We present optical characterization and laser results achieved with single-crystal fibers directly grown by the micro-pulling-down technique. We investigate the spectroscopic and optical quality of the fiber, and we present the first laser results. We achieved a cw laser power of 10 W at 1064 nm for an incident pump power of 60 W at 808 nm and 360 kW peak power for 12 ns pulses at 1 kHz in the ...
متن کاملDirect amplification of ultrashort pulses in μ-pulling-down Yb:YAG single crystal fibers.
We demonstrated that Yb:YAG single crystal fibers have a strong potential for the amplification of femtosecond pulses. Seeded by 230 fs pulses with an average power of 400 mW at 30 MHz delivered by a passively mode-locked Yb:KYW oscillator, the system produced 330 fs pulses with an average power of 12 W. This is the shortest pulse duration ever produced by an Yb:YAG amplifier. The gain in the s...
متن کاملA Brief Opinion on Pulling Down Briefs.
Digital rectal examination (DRE) is stressed in medical training as an integral component of genitourinary evaluation. Criticism regarding this examination is, to most physicians, much ado about nothing. However, DRE is considered by many patients to be a truly invasive test, and therefore its role should be critically evaluated, as with any other medical test and procedure. In this spirit, a d...
متن کاملDirectional solidification of the eutectic LiF-LiYF4 using Bridgman and micro-pulling down techniques: Microstructural study and some properties
The eutectic LiF−LiYF4 has been solidified by Bridgman and micro-pulling down (mPD) at pulling rates from 4 to 300 mm/h. The microstructure changes from a coupled, interpenetrated-like one to macrofaceted colonies composed of an approximately triangular arrangement of LiF fibers inside the LiYF4 matrix as the pulling rate increases. The cross-over pulling rate is around 3 times larger for the m...
متن کاملQuantification of the tug-back by measuring the pulling force and micro computed tomographic evaluation
Objectives The aims of this study were to quantify tug-back by measuring the pulling force and investigate the correlation of clinical tug-back pulling force with in vitro gutta-percha (GP) cone adaptation score using micro-computed tomography (µCT). Materials and Methods Twenty-eight roots from human single-rooted teeth were divided into 2 groups. In the ProTaper Next (PTN) group, root canal...
