摘要： The present invention provides an electrooptic Q-switch element made of a single crystal. The invention includes a langasite (LGS) single crystal and a reflection element located on one side of the langasite crystal along the light propagation direction. A light beam penetrates the LGS crystal along the main optical axis, is reflected by the reflection element, and passes through the LGS crystal again, so that the rotation angle of the polarization plane of the light originating from the optical activity is zero degrees. One advantage of the electrooptic Q-switch is its low, adjustable, high stable half-wave voltage. The invention can overcome the problems associated with current commercial Q-switches, such as high, non-adjustable, low stable half-wave voltage and great half-wave voltage variation with temperature.

摘要： An apparatus and method for an efficient, passively Q-switched microlaser producing high peak power pulses of light of extremely short duration are disclosed. This microlaser utilizes Yb3null:YAG as the gain medium instead of conventionally used Nd3null:YAG or Nd3null:YVO4 gain media The utilization of the Yb3null:YAG allows superior performance of high peak-power microlaser in many aspects with respect to conventionally used Nd3null:YAG as the gain media. The efficiency of the pump of said microlaser (the so called optical-to-optical efficiency) can be higher by factor of two to four, with respect to Nd:YAG based, provided all other output parameters such as pulsewidth, output peak power and spatial quality of the beam being equal. The improved efficiency allows reducing the cost and size of the whole microlaser system substantially. In addition to lowering the cost of the microlaser system by factor of two to three, the temperature stability of the proposed microchip laser improved by factor of 5, due to the wider absorption bandwidth of the Yb3null:YAG to those of Nd3null:YAG or Nd3null:YVO4.

摘要： A Q-switched microlaser is provided that is capable of supporting a zig-zag resonation pattern in response to side pumping of the active gain medium so as to effectively lengthen the microresonator cavity without having to physically lengthen the microresonator cavity. As such, the microlaser can generate pulses having greater pulse widths and correspondingly greater pulse energies and average power levels than the pulses provided by conventional microlasers of a similar size. A corresponding fabrication method is also provided according to one embodiment of the present invention that permits a plurality of side pumped Q-switched microlasers to be fabricated in an efficient and repeatable manner.

摘要： A novel Q-switch device enable significant quality and value improvement for a Q-switched laser system by achieving a significant reduction of mode-beating noise during the pulsed output. The origin of mode-beating noise in a Q-switched laser is a result of high gain availability and amplification of competing standing-waves in formation, whose optical frequency is a product of natural selection via spatial hole burning in the gain medium. The novel Q-switch device employs and active, electro-optics or acousto-optics. Q-switch in combination with a saturable absorber device, to provide an optimized soft opening of the optical path and a controlled timing of a Q-switched laster. This novel combination offers larger modulation loss than otherwise possible with the active modulator alone, and it allows for higher gain build-up energy extraction efficiency. Specifically, it will enable a low-voltage modulator ( 10) and Q-switched operation at high repetition rate (>10 kHz). The combination id devised to slow down the signal build-up and to sweep the fundamental longitudinal mode frequency at least within the free spectral range of the resonator, such that it varies adiabatically during the Q-switched pulse formation. A laser geometry amenable to high gain and high power is proposed for use in conjunction with the proposed novel Q-switch device. The invention will enable the deployment of cost-effective Q-switched lasers operating in both single-longitudinal and single-transverse (TEM00) mode.
