STABLE LiF:F+2 COLOR CENTER LASER OSCILLATION AT ROOM TEMPERATURE*
نویسنده
چکیده
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 color center laser.

We report experimental and theoretical studies of the temporal, spectral, and spatial features of a superbroadband laser. The results obtained show that the superbroadband room-temperature operable LiF:F(2)(-) color-center laser can provide low-coherence, high-intensity laser radiation with a spectral width of 1400 A centered at 1.14 mum and 700 A in the visible range from green to red and exhi...
متن کاملPowerful, room-temperature stable LiF:F2** tunable laser
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 t...

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...

In this article, the design and modeling details of room-temperature analog-to-digital converter (ADC) based on silicon quantum-dot (QD) single-electron transistors (SETs) is presented. In contrast to the conventional metal quantum dots, the use of silicon QDs in the scales of few nano-meters enhances the device operation and makes stable the Coulomb blockade and Coulomb oscillation regimes at ...
