چکیده

Instrument-limited suppression of out-of-band Amplified Spontaneous Emission (ASE) is demonstrated in a Nd:YLF Diode-Pumped Regenerative Amplifier (DPRA) using a Volume Bragg Grating (VBG) as a spectrally selective reflective element. A VBG with 99.4% diffraction efficiency and 230-pm-FWHM reflection bandwidth produced a 43-pm- FWHM output spectral width in an unseeded DPRA compared to 150-pm FWHM in the same DPRA with no VBG. Instrument-limited ASE suppression is even observed when the DPRA seed pulse energy approaches the ASE background.

LLE Review, Volume 91 103 Introduction The OMEGA facility is LLE’s 60-beam, 30-kJ (UV) laser system for performing inertial confinement fusion (ICF) experiments. One of the main features of the OMEGA laser is a flexible optical pulse–shaping system1 that produces 0.1to 5-ns, complex-shaped, low-energy pulses that must be amplified to ~1-mJ level before being injected into power amplifiers.

OPCPA pump laser based on a regenerative amplifier with volume Bragg grating spectral filtering

A novel Nd:YVO4−based regenerative amplifier system operating in the picosecond regime featuring a volume Bragg grating (VBG) as an intracavity spectral narrowing element is described. This compact amplifier provides pulses with duration of ∼85 ps operating at repetition rates ranging from single shot to 10 kHz. The VBG is used to passively tailor the pulse duration and achieve transformlimited...

Nd:glass diode-pumped regenerative amplifier, multimillijoule short-pulse chirped-pulse-amplifier laser.

We have built a diode-pumped Nd:glass regenerative amplifier that is able to produce energies up to 20 mJ within a 470-fs pulse duration at a 1-Hz repetition rate. We obtained this amplifier by using specific intracavity components such as a phase mirror and a birefringent filter to generate a large spatial mode and a large spectral width.

Regenerative spectral and pulse shaping of high average power chirped pulse thin-rod Yb:YAG amplifier

Spectral gain narrowing of high-average power, regenerative chirped pulse thin-rod Yb:YAG amplifier was compensated by the regenerative spectral and pulse shaping technique. An average output power of 18 W was achieved at a repetition rate of 100 kHz with an output pulse width of below 1.2 ps. A wide spectral bandwidth of 2.5 nm was also observed. 2009 Optical Society of America OCIS codes: (1...

Continuous-wave diode-pumped solid-state laser with an intracavity fiber Bragg grating.

We demonstrate the feasibility of a new concept of laser that benefits from both fiber and laser crystals: a cw diode-pumped solid-state laser with an intracavity fiber Bragg grating as the output coupler. The design of the laser cavity and the experimental demonstration are both described. Several applications are mentioned.
