JOURNAL FREE ACCESSThis paper describes a new method to change from quasi-CW CO2 Laser to repeated pulse type by variable curvature mirror. The variable curvature mirror is made of piezoelectric material Pb (Zr-Ti) O2 with polished thin brass plate as a mirror and forced to periodic vibration with applied A. C. voltage (frequency 3-9 kHz effective value 0-10 V). As a result the output of quasi- CW CO2 Laser changed to repeated pulse type, single or double pulses appear during one period of mirror vibration. The peak output of the pulse train is 10-35 times compared with quasi-CW output, and the duration of a pulse is 10 μs.View full abstractDownload PDF (721K) -

JOURNAL FREE ACCESSA technique is reported to obtain metal vapors by using the metal vapor-complex reaction in a low temperature region. This technique is applied to the pulsed copper-vapor-laser. By using this reaction of Cu+AlBr3, a copper-vapor-laser oscillations tarts at a room temperature, and the power output of the laser is found comparable with, or larger than the power operated by CuCl laser and operates without deposition of metallic copper to the discharge-tubew all.View full abstractDownload PDF (875K) -

JOURNAL FREE ACCESSThe very shallow junction of boron has been formed with the combination of ArF excimer laser and BF3gas. Since BF3gas is transparent at around 200 nm, boron atoms are obtained by pyrolysis of BF3gas. Sheet resistance can be controlled by the number of pulses and BF3 pressure under the condition of constant beam energy. From SEM analysis and Wright etching, any damages and defects are not observed on silicon surface at 1.2 J/cm2. Junction depths depend on the number of pulses, and the shallowest junction of -360Ådepth is obtained by 5 pulses. From the results of SIMS and four-point probe measurements, it is confirmed that nearly all boron atoms doped are electrically activated up to the concentration of 1020cm -3. Spatial uniformity within the irradiated area is also confirmed. A diode fabricated by laser doping shows a good I-V characteristics.View full abstractDownload PDF (831K) -
