Self-stabilized single-longitudinal-mode operation in a self-Q-switched Cr,Nd:YAG laser.
Single-longitudinal-mode operation in a homogeneously broadened solid-state laser is often impeded by spatial hole burning. To maintain a single longitudinal mode, it is necessary to eliminate spatial hole burning, for example, by introducing quarter-wave plates at both ends of the gain medium' or by using a ring cavity.2 In a standingwave resonator, an additional wavelength-selective element, ...
متن کاملUltrashort Q-switched pulses from a passively mode-locked distributed Bragg reflector semiconductor laser.
A compact semiconductor mode-locked laser (MLL) is presented that demonstrates strong passive Q-switched mode-locking over a wide range of drive conditions. The Q-switched frequency is tunable between 1 and 4 GHz for mode-locked pulses widths around 3.5 ps. The maximum ratio of peak to average power of the pulse-train is >120, greatly exceeding that of similarly sized passively MLLs.
متن کاملPassively Q-switched mode-locking of Tm:YAP laser based on Cr:ZnS saturable absorber.
Using a Cr:ZnS wafer as the saturable absorber, diode-pumped passively Q-switched mode-locking of a Tm:YAP laser at 1976 nm has been realized for the first time, to the best of our knowledge, and nearly 100% modulation depth of Q-switched mode-locking was achieved. The width of the mode-locked pulse was estimated to be about 980 ps with a repetition rate of 350 MHz within a roughly 300-ns-long ...
متن کاملSwitchable pulses generation in passively Q-switched multilongitudinal-mode microchip laser
Periodical switching laser pulses with nanosecond pulse width and several kilowatts peak power from wideseparated multilongitudinal-mode oscillation were observed experimentally in laser-diode pumped passively Q-switched Yb:YAG microchip laser with Cr:YAG as saturable absorber. Pulses from different longitudinal modes oscillate alternatively. Periodical pulses oscillation dynamics induced by sp...
متن کاملSimultaneous Mode Locking in a Diode-Pumped Passively Q-Switched Nd:YVO(4) Laser with a GaAs Saturable Absorber.
Simultaneous mode locking and Q switching is accomplished in a diode-pumped Nd:YVO(4)/GaAs laser. The average output power is ~2.0 W at 10.6-W absorbed pump power, and the repetition rate of the Q-switched pulse is ~120 kHz. The mode-locked pulse inside the Q-switched pulse has a repetition rate of ~148 MHz, and its average duration is estimated to be ~100 ps.
