Micro-processing of Short-pulse and Ultrashort Pulse Lasers

lasers
The application of polarized lasers with compact, high power, and high beam quality in industrial and research applications such as micromachining and efficient harmonic production is growing. By optimizing the combination of factors such as crystal shape, cooling mechanism, and resonator design, 200mw laser pointer products like InnoSlab lasers and amplifiers exhibit the following advantages: short pulse width, high peak power, high pulse repetition rate and high average power High beam quality. At the same time, they can also provide a high degree of flexibility for beam shapes, from circular beams to linear one-dimensional and two-dimensional flattened beams, to rectangular beams, and so on, providing added value for a wide range of special applications.

In order to achieve high beam quality and high output power at low cost, an innovative concept of lath lasers is proposed. (The semiconductors (diodes) are coupled to their linear beam shapes through resonant cavity mirrors. , The charge separation field can be as high as 100 GV / m, three orders of magnitude higher than the traditional RF accelerator, the ability to accelerate the charged particles to GeV energy in the order of centimeter distance, so the use of 300mw laser pointer accelerator to replace the traditional accelerator caused the scientific community Of the broad interest.
In many laser ion accelerating mechanisms, the ion beam obtained by the theory of Radiation Pressure Acceleration (RPA) has the characteristics of small scattering, high beam density and high energy conversion efficiency, which is the frontier and hotspot of the present research. Although RPA theory and one-dimensional simulation results are very attractive, but the experiment is also difficult to obtain the desired good results. The most important reason is that the instability of the high-dimensional conditions under the dramatic development.
Using the same pump solution, slat geometry and optical mirror configuration, excellent multi-channel amplifiers can be obtained. Advantages of InnoSlab burning laser pointer amplifiers include its large amplification factor, high efficiency power and energy extraction, power and energy scalability, and retention of seeding properties (beam quality, pulse width, etc.). This makes the ultra-short pulse to achieve kilowatts of power and multi-joule of energy.
Sub-surface engraving. By focusing the short pulsed laser beam into the glass block, the pulse energy is absorbed to a large extent in the focusing region, causing the material to melt and evaporate. Due to the mechanical stress associated with melting and evaporation, cracks of 100 μm in size are produced in the glass and are visually recognized as mark points. In this way, you can achieve the logo and trademark sub-surface marking. Compared to sub-surface engraving, the focus is on the bottom surface when the glass is cut and drilled. In this way, it is possible to realize high-precision, repeatable and high-speed glass processing. By using a Q-type InnoSlab 500mw laser pointer with a frequency of 100 kHz, a volume ablation rate of> 1.5 mm3 / s can be achieved. The process has been used in shower applications such as glass plates, glass covers and contact holes on solar panels.
Cutting and grinding glass, the use of high-power picosecond lasers combined with layer-by-layer ablation process to achieve the overall cut of glass or sapphire pieces. The use of 250W picosecond high power laser pointer can achieve up to 2mm3 / s volumetric ablation rate; cutting transparent and brittle materials, a sub-surface engraving process can be used to separate transparent and brittle materials such as glass and sapphire. The method is also known as filamentous cutting and is widely used for the separation of sapphire and glass plates. Typical thickness of sapphire or glass plate <0.7mm. Cutting edge of high quality, crack less than 5μm. Cutting speed of up to several meters / second.
