Shanghai Dream Lasers Technology Co., Ltd. provide different customers (science users, commercial customers and industrial manufacturers, etc.) with up to date laser source and complete solutions in a wide range of lasers applications in scientific research, biomedicine, and environmental sciences to industrial materials processing, microelectronics and entertainment.
 

1. Industrial and Manufacturing (Laser Processing)

• Cutting and Welding: Precision processing of metals, plastics, ceramics (e.g., automotive and aerospace industries).

Battery pack welding, (such as CATL, BYD battery production line).
Wafer cutting and processing, (such as Stealth Dicing and Laser Grooving).

• Drilling and Cleaning: laser cleaning electrode surface oxide, Via Drilling, Debonding, (Such as Chiplet technology in advanced packaging)
• Charging system: laser wireless charging technology (experimental stage), through the laser long-distance transmission of power.
• Fault detection: laser ultrasound is used to detect internal defects of the battery (such as lithium, crack).
• Lithography: DUV, EUV and Laser Direct Imaging, LDI.
• Laser Annealing: Such as FinFET transistor manufacturing and OLED display driver chip.
• Laser Induced Breakdown (LIBS): Such as detect the composition of wafer surface contaminants such as metal residues. e.g., 266 nm, 355 nm, 532 nm, 1064 nm, etc.
• Laser Repair: Fix defective circuits in DRAM or OLED displays (such as cutting off short-circuit nodes or depositing conductive materials)
• Advanced material processing: Laser cutting/etching wide band gap semiconductor materials (traditional mechanical processing is easy to cause fragmentation) e.g., Silicon Carbide and Gallium nitride.
• Laser peeling, patterning, for flexible electronics or sensors. e.g., Two-dimensional materials such as graphene.
• Marking and Engraving: Diamond Marking and Planning (1064nm) permanent markings on electronics, jewelry, etc. (e.g., QR codes, logos).
• 3D Printing: Selective laser sintering (SLS) or laser cladding.
• Micromachining: Micro/nano-scale processing of semiconductor chips and precision components.

2. Medical Treatment and Biotechnology

• Surgery: Laser scalpels (e.g., LASIK eye surgery, tumor removal, Laser ablation, illumination of the endoscope), dentistry (cavity treatment), urology, vascular surgery.
• Cosmetology:
• I. Hair removal: Laser selectively targets melanin in hair follicles, generates heat energy to destroy hair follicles and inhibit hair regeneration, such as Candela GentleLase Pro 755nm, Soprano ICE 810nm, for darker skin, Fotona 4D 1064nm, multi-function).

II. Skin rejuvenation & freckle, the laser selectively destroys melanin (such as freckles, melasma, senile spots) or ink particles (tattoos). Commonly used laser: Q-switched Nd:YAG laser (1064nm/532nm) -- deep/light pigment. Picosecond laser (Picosure/Picoway) - shorter pulse width, less thermal damage.
III. Non-ablative rejuvenation (stimulates collagen regeneration). Laser heating of the dermis promotes remodeling of collagen and elastic fibers. Fractional Laser (such as CO₂ laser, Er:YAG laser) Non-ablative laser (1550nm erbium glass laser) - short recovery period. Such as Fraxel (1550nm fractional laser) PicoWay (picosecond laser, freckle + rejuvenation) Ultra-pulsed CO₂ laser (exfoliative peeling)
IV. Laser acne & acne seal repair
(1) Acne treatment such as Blue light (405-420nm) + red light (630nm): bactericidal + anti-inflammatory.
Photodynamic therapy (PDT) combines photosensitizers to inhibit sebaceous glands.
(2) Pit repair
Fractional CO₂ laser: stimulates collagen remodeling and improves depressed scars.
Laser generation (low energy laser therapy, LLLT): 650nm-680nm red/near-infrared laser irradiates the scalp to enhance hair follicle metabolism, promote blood circulation, and delay hair loss. Such as Laser hair growth caps (e.g. iRestore, Theradome) Clinical-grade LLLT equipment (e.g. HairMax laser comb)
V. Laser vascular therapy (removing red blood stains and rosacea): Pulsed dye laser (PDL, 585nm/595nm) or KTP laser (532nm) targets hemoglobin and seals abnormal blood vessels.
Mainly application: Facial erythema, rosacea, hemangioma.
VI. Application of laser in hairdressing industry:
(1) Laser assisted hair dyeing
Some experimental techniques use lasers to open hair scales and enhance dye penetration (not yet commercially available).
(2) scalp health management Low energy laser (LLLT) is used to improve scalp inflammation and promote hair growth.
Future Trends
AI+ laser beauty: intelligent skin detection + personalized laser parameter adjustment.
Household laser equipment: such as depilator (Silk 'n, Ulike), hair growth helmet.
Combined therapy: laser + radiofrequency (such as thermomaggi), laser + ultrasonic scalpel.

• Therapy: Photodynamic therapy (cancer treatment), laser acupuncture.
• Diagnostics: Confocal microscopy, Fluorescence microscope, flow cytometry (Flow cytometry has been widely used in immunology, hematology, oncology, cell biology, cytogenetics, biochemistry and other clinical and basic medical research. Common Wavelength: e.g., 375nm, 405nm, 450nm, 488nm, 520nm, 532nm, 561nm, 640nm, 660nm, 780nm, etc.).
• Neuroscience: Laser optogenetics (Brain Stimulus Illumination System).

405nm, 457nm, 532nm, 561nm, 577nm, 589nm, 635nm, 808nm, Multi-wavelength laser, etc.
