چکیده
A powerful photoand thermostable, LiF:Fj** color center laser pumped by radiation at 740 nm (alexandrite laser) or at 683 nm (Raman shifted (H2) second harmonic of a Nd:YAG laser) is described. This is the first time an average power as high as —1.4 W and an energy per pulse as high as 1OOmJ, with record real efficiency of 53% (683 nm pumping) and 28% (740 nm pumping) were achieved for a room temperature LiF:Fj** color center laser. Such color center laser, tunable in the 82

Powerful ultrabroadly tunable LW:F2+** laser
The LiF:F2+** laser has been shown' to provide high power (hundreds ofmJ), efficient (tens of%), room temperature stable laser operation tunable from 800 nm to nearly 1210 nm. However, no reasonable explanations were provided for such an ultrabroadband tuning capability using this active medium. This work describes the mechanism ofthe ullrabroadband lasing from LiF:F2+** und Alexandrite 1asa pu...
متن کاملTunable distributed feedback color center laser using stabilized F2 +** color centers in LiF crystal
The first room temperature stable tunable color center (CC) distributed feedback (DFB) laser is described. The laser utilizes stabilized F2 +** centers in LiF (LiF:F2 ) as a gain medium. Tunable DFB lasing was achieved in the near IR region (882 962 nm) with a lasing linewidth of less than 0.2 cm. The lasing threshold was found to be 1.2 mJ, while the slope efficiency with respect to pump energ...

The laser utilizing LiF crystal with F2 color centers (CC) is an efficient and reliable source of tunable radiation which covers a broad near IR spectral region that is very important for scientific applications and allows using CC lasers for spectroscopic investigations of rare earth doped laser materials [1]. The CW operation of LiF:F2 CC laser is complicated due to short lifetime of F2 CC (5...
متن کاملOpto-VLSI-based tunable single-mode fiber laser.
A new tunable fiber ring laser structure employing an Opto-VLSI processor and an erbium-doped fiber amplifier (EDFA) is reported. The Opto-VLSI processor is able to dynamically select and couple a waveband from the gain spectrum of the EDFA into a fiber ring, leading to a narrow-linewidth high-quality tunable laser output. Experimental results demonstrate a tunable fiber laser of linewidth 0.05...
متن کاملSTABLE LiF:F+2 COLOR CENTER LASER OSCILLATION AT ROOM TEMPERATURE*
An LiF:F+2 color center laser using a two-mirror cavity is reported. The LiF:F+2 laser was achieved by creating the F+2 centers through the photoionization of the F2 color centers at room temperature and simultaneously by exciting the F+2 centers optically. We obtained the F+2 broadband laser oscillation with a peak at 930 nm, and it was more powerful than the room-temperature broadband LiF:F+3...
