چکیده

We experimentally demonstrated the manipulation of 2 μm linearly polarized states in a diode-pumped YAG/Tm:YAG/YAG laser with high polarization extinction ratio of 28 dB for the very first time to the best of our knowledge. A stable linearly polarized state of 2 μm was achieved without using any specific intracavity optical polarization-selected elements. The unexpected phenomenon of tunable linear polarization directions was observed. Multidistinct linear polarization directions were experimentally obtained, including the peculiar case of switchable orthogonally linear polarization directions.

Experimental Study of a Flash-lamp Pumped Passively Q-Switched Nd:YAG Laser Using Cr4+:YAG Saturable Absorber

This paper deals with the experimental results of a xenon flash-lamp pumped passively Q-switched Nd:YAG laser using Cr4+:YAG saturable absorber. The need of a laser cavity to be integrated into a time-of-flight laser range finder is of great interest as an experimental investigation of several laser resonators. Two types of laser resonator, with different lengths, have been studied: the flat-fl...

Diode edge-pumped passively Q-switched microchip laser

There is an increasing demand for high-intensity subnanosecond lasers for emerging industrial applications. While femtosecond and picosecond laser sources are considered promising, they suffer from the significant drawbacks of increased complexity and cost. In this regard, we demonstrate a unique edge-pumped passively Q-switched Nd∶YAG∕Cr4þ∶YAG microchip laser. The microchip is made of a Nd∶YAG...

Saturable Bragg reflector self-starting passive mode locking of a Cr(4+):YAG laser pumped with a diode-pumped Nd:YVO(4) laser.

We demonstrate self-starting passive mode locking of a Cr (4+):YAG laser, using an intracavity nonlinear mirror as a saturable absorber. The pump source is a diode-pumped Nd:YVO(4) laser. Output pulses are centered at 1541 nm, with 26-nm spectral bandwidth and 110-fs pulse width. Output powers of 70 mW are obtained with 8 W of pump power. This mode locking technique is compared with Kerr-lens m...

Passively Q-switched ceramic Nd3+:YAG/Cr4+:YAG lasers.

Passively Q-switched ceramic Nd3+:YAG lasers with ceramic Cr4+:YAG saturable absorbers are demonstrated. When the lasers are pumped by a 1-W cw laser diode, optical-optical efficiency as great as 22% is obtained with Cr4+:YAG of initial transmission ranging from 94% to 79%. The results are similar to those in their crystalline counterparts. The operation of Brewster's angle and the polarization...

We report 56% efficient external cavity resonant second harmonic generation of a diode-laser pumped, CW single-axial-mode Nd :YAG laser. A theory of external doubling with a resonant fundamental is presented and compared to experimental results for three monolithic cavities of nonlinear MgO : LiNb03. The best conversion efficiency was obtained with a 12.5 mm long monolithic ring cavity doubler,...
