STM

April 26, 2011

All of the instruments in the room for STM were set at their former positions. LCD and CRT displays fell to the ground but these worked in the correct way.

Mr. Fujita and Mr. Sato succeeded in taking STM images of a HOPG surface (left) and a gold nano particle (right).






Phase Separation

Mr. Shirasawa, Mr. Toyouchi and Mr. Kotaki restored nanosecond Nd:YAG lasers.

Mr. Kotaki checked his time-resolved Raman spectroscopy system (left). Second harmonic pulses irradiated a sample (right).






X-ray

Femto Second Laser 1


April 1, 2011
DSCF1057[1].jpg DSCF1040[1].jpg

A seed oscillator in a high power femtosecond laser system emitted light pulses.

A Nd:YLF pump laser radiated green light pulses (left) and an oscilloscope showed a regenerative amplifier waveform (center). Output power after a 2 path linear amplifier was 1.7 W at 2.5 kHz operation, and it's lower than it's before the earthquake. We should check and align all optical components.


Femto Second Laser 2


DSCF1097[1].jpg

An oscilloscope showed another seed oscillator worked, but the oscillator was unstable.




Room for Optical Measurement

April 13, 2011

DSCF1157[1].jpg

We cleaned the room for optical measurements.

Conventional UV-visible absorption and fluorescence spectroscopy systems were restored. Mr. Tomita tried taking absorption and fluorescence spectra of anthracene in ethanol.





Room for Chemicals

April 22, 2011

DSCF1151[1].jpg

Broken glass ware was cleaned.




Meeting Room

April 22, 2011

DSCF1135[1].jpg DSCF1136[1].jpg DSCF1137[1].jpg

We cleaned our seminar room (left). Tap water and city gas supply started so we could boil water and make some coffee (right).

Each student has cleaned their desk and their room.
