Nick: Sveta, I’m looking for Boris. Have you seen him today?
Sveta: Yes, he is making a hologram in the lab.
Nick: Is he? And 1_______?
Sveta: Look at your watch! See? 2_______. It is produced when laser light is recorded on a holographic plate.
Nick: I can’t imagine Boris experimenting with a laser beam.
Sveta: Well, just ten minutes ago I saw him splitting the laser beam into two separate beams by means of a beam splitter.
Nick: As far as I can see, it’s rather difficult to make a hologram.
Sveta: Oh, it is not. If you have all necessary equipment you can make holograms at home.
Nick: Really? What equipment do I need?
Sveta: Well, the easiest hologram requires 3_______, a lens, a holographic plate, a stable table, a dark room with green safe-lights and a holographic model. Of course, you are supposed to know what to do with this equipment.
Nick: Right. Where can I learn how to make holograms?
Sveta: If you are so interested, you can join our 4_______. By the way, Boris is still in the lab. You can watch him producing a hologram right now.
Nick: Indeed. See you at the Club tomorrow then.

Teacher: Hello, my friends. Today, I’m going to show you an operating 1_______.
Ivan: That’s great! By the way, what does the word “laser” mean?
Teacher: 2_______. Looking at the operating laser one can see it producing a very powerful beam of light.
Ivan: When did the first lasers appear, I wonder?
Teacher: As far as I know, in the 1960s. Yet, we hear of their having numerous applications. 3_______.
Ivan: And how do lasers work?
Teacher: Their work is based on the principle of amplifying the light of a certain wavelength in the resonator cavity.
Ivan: I’m rather interested in making experiments with laser beams.
Teacher: Then let’s try to make one. But be very careful. Lasers can be very 4_______.
Ivan: Why are they dangerous?
Teacher: Well, they produce a very powerful beam of light and if treated in the wrong way it can hurt or even kill you.
Ivan: Oh, I’m pretty scared.
Teacher: Don’t worry. If you follow all the safety instructions nothing will happen to you.
