Disclosed are a cooking material dispensing system and dispensing method. The dispensing method comprises the following steps: setting a material bag () clamping station in a position near a cooking pot opening but outside the range of the pot opening, and clamping the material bag () containing a cooking material at the material bag () clamping station; confining the material bag (), such that the material bag () is kept in a clamped state to control the deformation thereof during the dispensing procedure; flipping and/or tipping the material bag (), and when in a position near the cooking pot opening, dispensing the cooking material in the material bag () into the cooking pot; and once the cooking material has been dispensed, shifting the material bag () from the range of the cooking pot opening and releasing the clamping of the material bag (). The cooking material dispensing system comprises a dispensing device capable of clamping, confining, and transferring the material bag () and flipping the opened material bag and/or tipping the cooking material into the cooking pot. The dispensing system and dispensing method take a material packaged in the material bag () and can accurately move the material bag () into the dispensing position, making the cooking process convenient, fast and simple, and the entire process will not be contaminated.

Corner pumping method and gain module for high power slab laser are disclosed. In one embodiment, said method comprises directing a pump light from one or more pump light sources each consisting of a high power diode array and its coupling system into a laser slab through prior cut slab corners of said laser slab without restriction to the incident angle or the polarization state of the pump light, wherein said laser slab includes an undoped circumambient portion and one or more doped central portions; propagating said pump light within the laser slab by total internal reflection (TIR), wherein said pump light firstly pass said undoped circumambient portion, secondly pass said doped central portion, thirdly pass said undoped circumambient portion again, and fourthly take inner reflection at the surface of said undoped circumambient portion, and by repeating these steps, achieve multi-pass absorption; and substantially absorbing the pump light during propagating. In another embodiment, said gain module comprises a laser slab formed by solid state laser material, said laser slab including an undoped circumambient portion and one or more doped central portions and prior cut slab corners with corner faces; and one or more pump source providing a pump light; wherein said pump light is directed into said laser slab through said slab corners of said laser slab, propagated within said laser slab and substantially absorbed during propagation; and wherein said laser slab outputs an amplified laser beam.
