A stable Q-switch pulse train is obtained, with an operational wavelength range from 1056.6-1083.3 nm. Concurrently, a maximum pulse energy and minimum pulse width as well as a.

BeamQ High peak power Erbium/Ytterbium co-doped pulsed fiber lasers are specially designed to address LIDAR and remote sensing applications. These lasers are an eye safe version, with a broad range of pulse widths and repetition rates, also peak power, energy per pulse and linear or random operation. 1550nm 1.5μm Pulsed Fiber Lasers are based on a MOPA configuration (Master Oscillator Power. The laser spectrum showed a high side mode suppression ratio of >30 dB and good long-term stability (center wavelength drifting within ±0.002 nm during 220 h of operation). Finally, our laser is delivered by a multimode fiber with power ~70 W, center wavelength of 794.77 nm, and spectral bandwidth of ~0.12 nm The laser source is a home-made pico-second Ytterbium doped fiber laser (repetition rate: 6.54 MHz and central wavelength: 1041.3 nm). By gradually changing the input power, a series of optical. ABSTRACTWe demonstrate a passively multi-wavelength Q-switched Ytterbium-doped fiber laser (YDFL) based on a multi-wall carbon nanotubes embedded in polyethylene oxide film as saturable absorber. The YDFL generates a stable multi-wavelength with spacing of 1.9 nm as the 980 nm pump power is fixed within 62. 4 mW and 78.0 mW. The repetition rate of the laser is tunable from 10.41 to 29.04 kHz. 1 µm, which is the wavelength of interest in Yb-doped fiber lasers. This property reduces cavity loss in a . 4 laser configuration and therefore reduces the threshold and increases the slope efficiency of the laser. Finally, optical fiber is a very long and thin cylinder with a very large surface-to-volume ratio, which allows for an exceptional capacity of heat dissipation when compared to.

CYFL-MEGA are Ytterbium fiber doped lasers providing a single mode operation. Thanks to the Keopsys patented design, they deliver a line width of few MHz up to 20 W of output power. These lasers perform a low relative intensity noise and a high optical po The Raman fiber laser adopted the dual-wavelength bidirectional pumping configuration, utilizing 976 nm laser diodes and 1018 nm fiber lasers as the pump sources. A 60-m-long $25/400~\unicode[STIX]{x03BC}\text{m}$ ytterbium-doped fiber was used to convert the power from 1070 to 1124 nm, realizing a maximum power output of 3.7 kW with a 3 dB spectral width of 6.8 nm. Moreover, we developed a.
