- the hard glass tube and the quartz tube have the following differences when compared in terms of materials.
- the hard glass tube is melted by mixing boric acid with silicon, which is the main component of the glass, to raise the softening temperature and hardness, whereas the quartz tube is basically made of only silicon.
- the life of the number of times of light emission of a general small flash lamp is tens of thousands of times for a quartz tube, whereas it is 3,000 to 10,000 times for a hard glass tube.

- the laser unit 200 covers the entire outer periphery of the flash lamp 230 with the lens barrel 210. For this reason, the temperature rise in the lens barrel 210 is extremely large, and if the flash lamp used as a strobe for a camera is used as it is, thermal damage will occur.
- this heat radiation countermeasure is taken by the supports 241, 242, 243, and 244 that support the flash lamp 230 on the unit main body 201.
- the flash lamp 230 is supported on the unit main body 201 by plate-like supports 241, 242, 243, and 244 disposed outside the lens barrel 210.

- the supports 241, 242, 243, and 244 are made of a material having high thermal conductivity such as aluminum. For this reason, the heat of the outer peripheral surface of the hard glass tube 231 (see FIG. 15) constituting the flash lamp 230 can be positively released to the outside of the lens barrel 210 via the support members 241, 242, 243, and 244. .
- the supports 241, 242, 243, and 244 are in close contact with the upper lens barrel 211 and the lower lens barrel 212. Thereby, the heat transmitted to the supports 241, 242, 243 and 244 can be radiated to the vent hole 205 via the upper barrel 211 and the lower barrel 212.
- the surfaces of the supports 241, 242, 243, and 244 facing the inner surface of the lens barrel 210 are mirror-finished to serve as reflecting surfaces.

That is, as shown in FIG. 8, the tip surface (the left side surface in FIG. 9) of the laser rod 220 is exposed to the condenser lens 207 side from the supports 241 and 243, so that dust adheres to the tip surface. Then, burn-in occurs.
- a space between the supports 241 and 243 of the lower case 202 and the condenser lens 207 is a sealed space 208 in which the upper surface opening of the lower case 202 is covered with the upper case 203.

- the rectangular notch part is easy to obtain processing accuracy when processing a metal (aluminum) member. Moreover, since there is a flat surface, assembly errors can be suppressed. It is difficult to obtain processing accuracy as high as the outer dimensions of the laser rod 220 and the flash lamp 230 in the round notch. If the processing accuracy cannot be obtained, the positional accuracy between the flash lamp 230 and the laser rod 220 cannot be maintained, and the laser output decreases. From the viewpoint of ease of implementation and cost reduction, a square cutout is used. However, it is needless to say that it may be a round notch.
