Continuous-wave mode-locked visible upconversion laser.
We describe continuous-wave mode locking and Q switching of an Er:LiYF(4) trio upconversion laser operating in the green spectral region.
متن کاملContinuous-wave, fourfold upconversion laser
Recent demonstrations 1-5 of room-temperature upconversion lasers have stirred interest in their potential as practical sources of short wavelength radiation for display and data storage applications, as well as for communications and ultrashort pulse generation at visible and ultraviolet wavelengths.6 To date however, little consideration has been given to the relative merits of various fundam...
متن کاملContinuous . . wave trio upconversion laser
The first laser to operate with an output wavelength shorter than that of the excitation was a pulsed erbium laser reported by Johnson and Guggenheim.l Since this early work, a variety of continuous-wave lasers have been reported in which upconversion occurs by different mechanisms, and inversions of upconverted energy levels have been sustained by avalanche processes, 2.3 direct pairpumping,4 ...
متن کاملDiode-pumped continuous-wave and passively mode-locked Yb:GSO laser.
We report on both continuous-wave and passively mode-locked laser actions of a new ytterbium-doped laser crystal Yb:Gd(2)SiO(5) (Yb:GSO) under high-power diode-end-pumping. Due to the anisotropic and compact crystal structure, Yb:GSO exhibits a large manifold splitting of Yb(3+) ions, and a Yb:GSO laser can be operated efficiently with negligible reabsorption losses at emission wavelengths. In ...
متن کاملContinuous-wave mode-locked Nd:glass laser pumped by a laser diode.
We have demonstrated a diode-laser-pumped, cw, mode-locked Nd:glass laser oscillator. With a 0.5% output coupler the pump threshold for mode-locked operation was 22.9 mW. The mode-locked pulse width was shorter than 36.5 psec, which was the response time of the fast photodiode and the sampling oscilloscope. Diode-laser-pumped mode-locked operation was also extended to Nd:YAG.
