Q-switched Nd:Ce:YAG+Cr4+:YAG Beauty Laser
1.Bonding crystals were water-cooled
①Repetition frequency --- Improves repetition frequency of the laser equipment from 3 cycles/second to 8 cycles/second.
②Enhance apparatus lifetime --- It improves the life of the Q-crystals. Q-crystals cool naturally and thus it may easier get burnt when overheated. Life of Q-crystals shall be improved at least double if they are using bonding crystals.
③Improve efficiency. Bonding crystals can improve the efficiency at least 20% of the laser equipment. During the laser amplification process, it will have only 2 light transmission surfaces. If bonding crystals apply, there will have at least 5 surfaces. It can minimize loss and advance efficiency.
④Steady output. Energy output is more steady while using with bonding crystals.
2. Encapsulation composited by bonding crystals least pulse width to reach 5ns with maximum output at peak efficiency
①No commissioning required. No adjustment require for laser equipment when bonding crystals used. Once installed, the bonding crystals apparatus can be used without any maintenance.
②Less errors. Minimum manual errors that affect output efficiency due to adjustment.
③No extra manpower. Minimize manpower costs as it doesn’t require the process to adjust the laser.
④Compact size. No front/rear lens, Q-crystals and lens holder require. Total space in the encapsulation can be minimized to be more compact and miniaturized (some customers are using the concepts to produce small handheld laser equipment.).
⑤Mechanically stable. Conventional crystals utilize many others components in the encapsulation body. They are suffered from the effects of vibration, water temperature and environment. When they are being used for a period of time, their efficiency will be deteriorated until exhausted and thus they have to be maintained (re-adjustment). Bonding crystals can eliminate all the above failures. Once installed, no adjustment, never exhausted (until damage). When damage happens, customers can easily replace them. The bonding crystals can save logistic and manpower (maintenance) costs.
