This is a report on the mode-locking stability of a Kerr-lens mode-locked Ti:sapphire, measured by a newly developed noise measurement method. Mode-locking stability is monitored via a power spectrum, which is obtained by irradiating optical pulses o

Wafer-level packaging (WLP) is increasingly important for micro-electro-mechanical systems (MEMS) because of downsizing, cost reduction, and mechanical damage suppression during assembly. The diaphragms were fabricated using surface activated bonding

Frequency-tripled pulses at 290 nm from a 100-fs, 1-kHz Ti:sapphire regenerative amplifier system are spectrally broadened in hollow fiber filled with high-pressure argon gas. The self-phase-modulated pulses are compressed to 25 fs through a prism pa

Using THz radiation, a simple, noncontact, simultaneous method is applied to measure thickness and water content of black ink films independently from frequency-dependent and frequency-independent absorption characteristics of black ink films.

Using large-sized Li2B4O7 crystals, 0.43 J, 266 nm pulses are obtained from a 10 Hz Nd:YAG laser with a total conversion efficiency of 30.5%. Moreover, 4 W operation for over 15 h is demonstrated.

We developed AlGaAs photocathodes with low electron affinity for long negative electron affinity (NEA) lifetime. AlGaAs photocathodes achieved 10 times longer NEA lifetime than conventional NEA-GaAs photocathodes. We estimated the appropriate superla

Thermal receiver detectable terahertz (THz) radiation is generated from InAs irradiated with a 1040 nm, 80 fs, 180 mW, 48-MHz-repetition-rate mode-locked fiber laser in a 2 T field by a compact permanent magnet. THz radiation is monitored by means of

Time-resolved fluorescence measurements of malachite green dye molecules doped in onion cells were carried out. The fluorescence decay time was dependent on the individual cell and on the position of the dye in a cell, which reflect the microscopic d
