The most common DPSSL in use is the 532 nm wavelength green laser pointer. A powerful (>200 mW) 808 nm wavelength infrared GaAlAs laser diode pumps a neodymium-doped yttrium aluminium garnet (Nd:YAG) or a neodymium-doped yttrium orthovanadate (Nd:YVO 4) crystal which produces 1064 nm wavelength light from the main spectral transition of ...
Since its founding, DPS R.K. Puram has maintained its standing as one of the most exclusive selective schools in India. [7] In 2014, for example, 2,800 applications were received for 140 Nursery school spots this year, yielding an admissions rate of only 5 percent, which–as The New York Times noted–rivals that of top universities in the United States.

Fig.1. An optically pumped disk laser (active mirror). A disk laser or active mirror (Fig.1) is a type of diode pumped solid-state laser characterized by a heat sink and laser output that are realized on opposite sides of a thin layer of active gain medium. [1]
This improved gain medium was central to the demonstration of the first tunable narrow-linewidth solid-state dye laser oscillators, by Duarte, [8] which were later optimized to deliver pulse emission in the kW regime in nearly diffraction limited beams with single-longitudinal-mode laser linewidths of ≈ 350 MHz (or ≈ 0.0004 nm, at a laser wavelength of 590 nm). [9]
Close-up of a table-top CW dye laser based on rhodamine 6G, emitting at 580 nm (yellow).The emitted laser beam is visible as faint yellow lines between the yellow window (center) and the yellow optics (upper-right), where it reflects down across the image to an unseen mirror, and back into the dye jet from the lower left corner.
The Laboratory for Laser Energetics (LLE) is a scientific research facility which is part of the University of Rochester's south campus, located in Brighton, New York.The lab was established in 1970 with operations jointly funded by the United States Department of Energy, the University of Rochester and the New York State government.
