Title: Effect of diode wavelength broadening in a diode end-pumped solid-state amplifier

Abstract

The effect of the spectral broadening in cw diode pumping and the wavelength shift in pulsed pumping of a solid-state laser is investigated theoretically.A very simple model allowing the computation of the reduction of the absorbed pump energy is developed.The results are applied to an ytterbium-doped solid-state laser and should be fruitful for amplifier and laser design.

  • An all-solid-state tunable diode-pumped Cr{sup 3+}:LiSrAlF{sub 6} (Cr:LiSAF) regenerative amplifier, seeded by a tunable diode-pumped Cr:LiSAF femtosecond oscillator, has been demonstrated for the first time to our knowledge. The oscillator was tunable over 75 nm and generated pulses as short as 24 fs. As much as 70 mW average output power was obtained with pulses of 40-fs duration. The amplifier produced recompressed pulses of less than 200-fs duration with energies exceeding 1{mu}J at a repetition rate as high as 25 kHz. {copyright} {ital 1995} {ital Optical} {ital Society} {ital of} {ital America}.
  • The radiation intensity distribution of linear diode arrays used for longitudinal pumping fibre-coupled solid-state lasers is studied experimentally and theoretically. A simple model describing the propagation of radiation is proposed which allows the calculation of the inversion population distribution in an active element. The radiation intensity distributions are calculated in cross sections for different angular distributions at the fibre output. (lasers)
  • We describe a high-power compact diode-pumped Nd:YLF regenerative amplifier. The pumping source is a 15-W diode-laser array that is focused into the laser crystal with a longitudinal end-pumping arrangement based on an array of cylindrical microlenses. Seeded with 15-ps pulses from a diode-pumped and mode-locked Nd:YLF oscillator, the regenerative amplifier produces pulses of 0.5-mJ energy at a 1-kHz repetition rate. A pulse energy as high as 0.75 mJ is achieved at a 500-Hz repetition rate and below.
  • A tunable femtosecond solid-state amplifier system that uses only 3 W of 488-nm argon-ion pump power has been demonstrated to deliver microjoule pulses at repetition rates up to 20 kHz, with a maximum pulse energy of 14 {mu}J obtained at 5 kHz. An all-solid-state, tunable, diode-pumped Cr:LiSrAlF{sub 6} regenerative amplifier has been demonstrated, for the first time to our knowledge, that amplifies femtosecond pulses to energies exceeding 1 {mu}J at up to a 16-kHz repetition rate.
  • Lasing is observed near 620 nm in a DCM dye doped TiO{sub 2}-content organically modified silicate (ORMO-SIL) pumped by frequency-doubled radiation from a diode-pumped {ital Q}-switched Nd:YAG laser. The laser wavelength is tunable over 60 nm. A conversion efficiency of 18{percent} is obtained at its central wavelength of 621 nm. The laser output energy has only a 10{percent} reduction after 27,000 pulses at a pump repetition rate of 30 Hz and a pump intensity of 1 J/cm{sup 2}. An all-solid-state, compact, long-lifetime, and tunable dye laser has been demonstrated. {copyright} 1997 Optical Society of America
