Molecular Iodine Spectra and Laser Stabilization by Frequency-Doubled 1534 nm Diode Laser
By using the second harmonic radiation of a 1543 nm diode laser, several predicted rovibronic transitions of molecular iodine were observed for the first time. We demonstrated that the absolute frequency of a 1534 nm external-cavity diode laser could be frequency-stabilized to a 1MHz instability (for one second averaging time) by locking the frequency of the second harmonic generation to the de...
متن کاملLaser cooling of beryllium ions using a frequency-doubled 626 nm diode laser.
We demonstrate laser cooling of trapped beryllium ions at 313 nm using a frequency-doubled extended cavity diode laser operated at 626 nm, obtained by cooling a ridge waveguide diode laser chip to -31°C. Up to 32 mW of narrowband 626 nm laser radiation is obtained. After passage through an optical isolator and beam shaping optics, 14 mW of 626 nm power remains of which 70% is coupled into an ex...
متن کاملTreatment of lentigines by a novel high power diode laser at 755 nm: a case report
The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...
متن کاملSub-50 ps pulses at 620 nm obtained from frequency doubled 1240 nm diamond Raman laser.
We report a monolithic 1240 nm diamond Raman laser producing pulses with duration of 42-62 ps at 100 kHz repetition rate, and maximum average power of 246 mW. The Raman laser is formed by a 0.5-mm thick planar diamond, coated on both sides and pumped by ~100 ps pulses from a Q-switched 1064 nm laser. The maximum conversion efficiency from 1064 nm to 1240 nm was about 25%. The 1240 nm signal was...
متن کاملFrequency doubling of He–Ne laser radiation at 632.8 nm
Second harmonic generation (SHG) obtained using a potassium dihydrogen phosphate (KDP) nonlinear crystal from a CW He–Ne laser as a pump source, which emits at 632.8 nm, is reported. The SHG efficiency at the power of the He–Ne laser utilized (18 mW) and the fundamental beam waist available (0.1 mm), was evaluated theoretically; the same efficiency was measured experimentally obtaining a value ...
