چکیده
We report room-temperature operation of what we believe is the first continuous-wave laser that relies exclusively on cooperative upconversion by coupled ion pairs to achieve population inversion.

متن کاملTime-bin entangled photon pair generation from Si micro-ring resonator.
We demonstrate time-bin entanglement generation in telecom wavelength using a 7 μm radius Si micro-ring resonator pumped by a continuous wave laser. The resonator structure can enhance spontaneous four wave mixing, leading to a photon pair generation rate of about 90-100 Hz with a laser pump power of as low as -3.92 dBm (0.41 mW). We succeed in observing time-bin entanglement with the visibilit...
متن کاملContinuous-wave operation of a room-temperature, diode-laser-pumped, 946-nm Nd:YAG laser.
Single-stripe diode-laser-pumped operation of a continuous-wave 946-nm Nd:YAG laser with less than 10-mW threshold has been demonstrated. A slope efficiency of 16% near threshold was shown with a projected slope efficiency well above a threshold of 34% based on results under Rhodamine 6G dye-laser pumping. Nonlinear crystals for second-harmonic generation of this source were evaluated. KNbO(3) ...

We demonstrate an electrically pumped silicon evanescent laser incorporating AlGaInAs quantum wells with a silicon waveguide. The device operates continuous wave with a threshold of 65 mA and a fiber coupled output power of 1.8 mW.
متن کاملDirect diode-pumped Kerr-lens mode-locked Ti:sapphire laser
We describe a Ti:sapphire laser pumped directly with a pair of 1.2 W 445 nm laser diodes. With over 30 mW average power at 800 nm and a measured pulsewidth of 15 fs, Kerr-lens-modelocked pulses are available with dramatically decreased pump cost. We propose a simple model to explain the observed highly stable Kerr-lens modelocking in spite of the fact that both the mode-locked and continuous-wa...
