Disclosed is drug delivery system for effectively administering a drug into a human or animal body tissue. The microjet drug delivery system includes (a) a microjet injector including: a pressure chamber partially sealed by an elastic membrane and containing a pressure-inducing liquid fluid-tightly filled therein; and a drug chamber adjacent to the pressure chamber, wherein the elastic membrane is disposed between the pressure and drug chambers, wherein the drug solution is contained in the drug chamber, wherein the drug chamber has a micro-nozzle partially defined in a wall thereof for ejecting the drug solution out of the drug chamber; (b) a laser generator for generating a laser beam and emitting the laser beam out of the laser generator, wherein the laser generator is configured by irradiating the laser beam into the pressure-inducing liquid in the microjet injector, thereby generating a bubble in the pressure-inducing liquid; and (c) a fractional laser filter module configured for splitting the laser beam incident from the laser generator into a plurality of fractional laser beams, each beam has a reduced diameter, and for irradiating the fractional laser beams. According to the microjet drug delivery system, the pre-ablating of the skin with the fractional laser beams to partially remove the stratum corneum may enable the drug microjet based injection to allow the drug to be effectively invaded into a skin tissue at the portion where the stratum corneum is partially removed and relatively softened.

The invention relates to a skin treatment device (10) for fractional treatment of the skin (100) of a human being. A radiation source (5) emits a multi-mode laser beam (20) with a superposition (23) of mutually different higher-order laser modes. The multi-mode laser beam is configured by said superposition of different laser modes to simultaneously cause a first plurality of high-intensity zones,where the thermal threshold (TC) for collagen denaturation for the treatment zone (50) of the skin is at least reached, and a second plurality of low-intensity zones where the thermal threshold (TF)for fibroblast stimulation for the treatment zone of the skin is at least reached. This is advantageous for obtaining a skin treatment device with a simple and therefore low-cost fractional laser skintreatment system for combined collagen denaturation and fibroblast stimulation. The skin treatment device is based on non-uniform laser radiation in the form of the multi-mode laser beam.

The invention is an all-optical Rb frequency standard method and system. The method: firstly, adjusting the pump laser to the wavelength corresponding to Rb D2 line; then modulating semiconductor laser by radio signal to produce optical component needed to excite coherent resonance, and using two proper side bands to excite Rb 0-0 ultrafine coherent resonant transition; when the frequency of fine crystal oscillator deviates, the atomic system outputs a deviation correcting signal to control VCO, to make the VCO return to original frequency. The system is composed of semiconductor laser diode, Rb atomic physical system, optical signal detecting and amplifying device and high-precision constant temperature VCO, which are linked with one another. It uses Rb atomic coherent resonant transition chart line to identify the frequency, and the frequency locking is higher; needs no mechanical exciting system, avoiding the effect of mechanical system; uses commercial fractional laser diode as excitation source.
