Dear Valuable Partners:

Rainy season has started here in Tokyo, but our business is solid as usual. We hope you had an
opportunity to take a look at our recent advertisements in Photonics Spectra, either paper or on
line. After 40+ years, the wavelengths of HeCd laser is still unique. There are still gold mines out
there for all of you to work on while waiting for new products from Kimmon. Soon you will be
asked a question whether or not you wish to represent Kimmon for the new products. We will be
selective in terms of our global network for the new products, so please also advise us reasons
why you are interested in the new products from Kimmon. See you soon.

Campaign Information

We offer IK3102R-G JPY2,000,000(net price).
We also offer free power meter.
Please list in your PO "IK3102R-G with free power

Offer valid until July 31, 2014.
Looking forward to your P.O.


As you may know, the old power supply over ten years cause many troubles. For example,
the fan stops suddenly, or high voltage parts degrated and stoped operation. And we
have released new power supply KP2014. This is the good oppotunity to suggest to change
new power supply. Try to contact your customer who uses our laser over ten years!

Thank you.



KIMMON KOHA will exhibit at Sapporo in September.

3) Blue/Violet Laser Application
4) He-Cd Laser Application
5) Publications Citing Kimmon HeCd Lasers
6) Exhibition information
7) New product information

Near future we will update more. We are planning to introduce information for only our
partners such a video manual for laser adjustment. The detail will inform you soon.

Application Note


Photoluminescence (PL) is a process which a substance absorbs light and then re-radiates
light. If a semiconductor is irradiated with a light which has energy greater than the band
gap, an electron in semiconductor is excited and a pair of electron and electron hole is
formed. Then more pairs are formed than when thermal equilibrium state. After that the
energy of excited electron is emitted as a light when the pair recombinants. And this
phenomenon is called photoluminescence. This emitted light is easy to be affected by
impurities and defects of substance. Therefore it can get information of impurities and
defects of substance by analyzing the details of light spectrum. Furthermore
photoluminescence method has an advantage to measure samples non-invasively, without
any pretreatments or electrode attachments. 325nm laser light of He-Cd laser is available to
measure lattice defects in GaN semiconductor crystal which are used for LED or blue LED.
There are two measuring methods in photoluminescence: one is mapping measurement
which measures the distribution of the power of emitted light from the sample, and the
other is spectrum measurement which measures the relation of power and wavelength.
Equipment of photoluminescence which measure crystal of light-emitting devices, LED or
blue LED, find out the existence or measure the distribution of defects and impurities, and
determine a pass/fail.


On December 4, 2013, traditional dietary cultures of the Japanese was registered in the
UNESCO intangible cultural heritage. In this year’s newsletter, we will introduce some
popular Japanese food.


Shabu-shabu, also spelled shyabushyabu)
is a Japanese dish featuring
thinly sliced beef boiled in water. The
term is an onomatopoeia, derived from the
sound emitted when the ingredients are
stirred in the cooking pot. The dish is
related to sukiyaki in style: Both consist of
thinly sliced meat and vegetables and
served with dipping sauces. However,
Shabu-shabu is considered to be more
savory and less sweet than sukiyaki.

History of Shabu-shabu

Shabu-shabu was introduced in Japan in the 20th century with the opening of the
restaurant "Suehiro" in Osaka, where the name was invented. Its origins are traced back to
the Chinese hot pot known as shuan yang rou. Shabu-shabu is most similar to the original
Chinese version when compared to other Japanese dishes (nabemono) such as sukiyaki
[citation needed]. Suehiro registered the name as a trademark in 1955. Together with
sukiyaki, shabu-shabu is a common dish in tourist hot-spots, especially in Tokyo, but also
in local Japanese neighborhoods (colloquially called "Little Tokyos") in countries such as
the United States and Canada.
