Chapter 167 Xu Qingzhou Can't Beat Me In the laboratory, 40 minutes passed. Xu Qingzhou further adjusted the parameter data of the device and said proudly: "This device is a linear resonant cavity. Its initial design cavity length is set to L=4m." "Generally speaking, when this value is , the compression of the quantum optical frequency comb is the highest." After he finished speaking, he found that the person next to him didn't react. He turned around and saw that Ren Xiaoling had a confused expression. He immediately realized that his pace was too fast and the brain cells of this senior sister were still reacting. "Don't understand?" "Well, there are too many knowledge points. I feel a little dizzy." Xu Qingzhou nodded and said, "Don't worry, just do a few more experiments and you will remember these things naturally." Ren Xiaoling was ashamed: "Brother, am I a little stupid?" "Is this your first time to complete this kind of experiment?" Xu Qingzhou asked while debugging the equipment.
"Ah." Xu Qingzhou turned around and comforted him, "That's right, just treat it as getting used to this hard life in advance. Your future 'boss' may be much more fierce than me." Strictly speaking, Ren Xiaoling is not a talented player. Not to mention compared with the geniuses he has seen before, even compared with Gong Yunfei, this senior seems a little dull. Advantages: Very motivated. With his own efforts, he was able to obtain a place in graduate school and was admitted to Professor Zhao's project, which has surpassed quite a few people. While chatting, Xu Qingzhou had already entered the next step. The output beam of the mode-locked femtosecond pulse laser is focused through optical elements such as lenses to ensure that the pump light can be efficiently coupled into the BiBO crystal. After 1 hour, everything was debugged and Xu Qingzhou pressed the start button. hum~ As Xu Qingzhou pressed the start button, the low sound of equipment running suddenly rang out in the laboratory. Ren Xiaoling held her breath and stared at the screen nervously. Xu Qingzhou was much calmer. As a king playing in a bronze game, with top-level inscriptions and top-level operations, the chance of failure was not high. However, compared with Ren Xiaoling's nervousness, he felt more emotional in his heart. This experiment was also the first physics experiment he actually presided over after his rebirth. Is this the first actual battle after returning to the invincible road? As the machine runs, the first data report is generated on the computer next to it. 【σ\sigma_= V^2 L = mm CR_1 = 8] Looking at the data in the computer, Xu Qingzhou nodded: "There is nothing wrong with the current data. The influence of the spatial walk-off effect on the compression degree is consistent with the theoretical prediction." "Huh~" Hearing this, Ren Xiaoling patted her chest with an excited expression. Xu Qingzhou said, "Okay, you can read a book or review the notes you just took." "No need to keep an eye on the machine?" Ren Xiaoling was a little worried. "With me here, nothing will go wrong."
Ren Xiaoling went to eat first, and came to take over Xu Qingzhou's shift at about 11:20. The experimental time is about 16 hours a day, and every 8 hours, different variables such as pump power, test temperature, transmittance of output mirror, etc. are adjusted according to the experimental plan. If nothing goes wrong, the experiment can be completed in 33 days. "It is important to keep the temperature stable, otherwise there will be problems with the data." Before leaving, Xu Qingzhou did not forget to remind him. In this experiment, the change in temperature will cause the thermal expansion and contraction effect of the material, which will in turn lead to a slight change in the cavity length, which may be difficult to observe with the naked eye, but the actual data will show very large fluctuations. "No problem." Ren Xiaoling looked serious and even took out a notebook to write down Xu Qingzhou's reminder. Xu Qingzhou smiled and shook his head, changed his clothes, took his phone and walked out of the laboratory. Breathing in the fresh air, he couldn't help but let out a long sigh. He didn't sleep well last night, and he was really tired at this time. At the same time, he did not forget to send a message to Song Yao, telling her that the experiment was successful. Song Yao: "Congratulations, eat early and go back to rest." "Quite aloof." Xu Qingzhou smiled gently, put away his phone, went to the cafeteria to eat, and then went straight back to the dormitory to catch up on some sleep. In the classroom, the professor is giving a lecture on the stage. Zhang Qiong had just finished taking notes when she noticed that Song Yao, who usually listened to the class attentively, was actually looking at his mobile phone, occasionally frowning with a serious expression. "This" Zhang Qiong thought this was really unusual. Xiaoyao actually started playing with her cell phone during class. Was she replying to Xu Qingzhou's message? It is said that a woman who falls in love will ignore everything. It would be terrible if Xiaoyao was really obsessed with love and couldn't extricate herself. Zhang Qiong thought worriedly and tilted her head to see what Song Yao was doing. Huh? Renting a house? What the hell? Zhang Qiong's mind was full of questions and she really wanted to get answers, but during class time, she had to put the questions aside. After 30 minutes, the get out of class was finally over, and Song Yao and Zhang Qiong walked towards the cafeteria. After leaving the teaching building, there were fewer people around, and Zhang Qiong said, "Xiaoyao, you played with your phone for the entire class." "Well, I finished reading the content of this class last semester." Song Yao was still looking at her phone. Xu Qingzhou's last message was sent 10 minutes ago, saying that he was going to catch up on some sleep. "." Zhang Qiong said she was very hurt and wondered why couldn't there be a normal person between the couple? One of them had published several SCI papers upon entering the school and had also solved a world-class mathematical problem. The other one was not only good-looking, but his grades were far better than those of other students in the major, and he finished two semesters’ worth of content in just one semester. This is so outrageous. How can ordinary people like them survive? She didn't even notice that she had started to change from being a hater to a fan, and was even developing into a bit of a CP fan. After being depressed for a while, she asked again in confusion: "Were you looking at the house while you were in class?" In the third and fourth years of college, some people want to rent a house to do internship or concentrate on preparing for exams. Renting a house is normal, but the first thing to consider is what kind of house to buy. "Yes, we want to rent a two-bedroom apartment near Peking University." Song Yao nodded in agreement.
Zhang Qiong stopped walking all of a sudden, with a look of shock on her face. She looked at Song Yao who had also stopped walking, and after a while of reacting, she shouted out, "You guys are going to live together?!" After she finished shouting, she realized that she was exaggerating. She carefully looked around and found that no one else heard it. She breathed a sigh of relief, but still felt that the news was too shocking. Song Yao raised her eyelids, her expression indifferent, and corrected: "It's renting together, not living together." The corners of Zhang Qiong's mouth twitched. No, is there any difference? The two continued to walk towards the cafeteria. "Xiaoyao, I understand how you guys feel about being in love, and you might be really into it, but you need to think carefully about this, since you're going out together and sharing a house." On the way, Zhang Qiong was talking when she suddenly saw Song Yao stop. She felt relieved. Did Xiaoyao also think that what I said made sense? Song Yao turned and looked at Zhang Qiong, her delicate and beautiful face full of seriousness and solemnity. "Xu Qingzhou can't beat me." "." (End of this chapter)
