The new state-of-the-art in high power, ultra-narrow bandwidth light generation. The ideal source for fast high resolution spectroscopic and LIDAR applications.

Description

The LAI 101 PAL-DLIS Diode Laser Injection Seeder is a revolutionary new way to control the frequency of tunable solid state-lasers. Typically, laser frequency is controlled by introducing intra-resonator loss using prisms, etalons or gratings. The unique DLIS system works by injecting photons of the correct spectral characteristics into the pulsed laser resonator. This provides the ultimate in high pulse energy frequency stabilized narrow bandwidth sources.

With the DLIS, our PAL™ laser systems provide tunable, nearly transform limited pulses, ideal for high resolution spectroscopy or LIDAR. Typical linewidths are under 200 MHz. With the frequency stabilization option the output frequency of the laser can be locked to atomic or molecular resonances, or to a scannable Fabry-Perot reference etalon. Output energy exceeds 350 mJ/pulse, and the high power output can be efficiently frequency converted with our wavelength conversion accessories to provide tunable narrow bandwidth light at almost any wavelength.

Avoid fiber damage! Control laser material interactions! Now laser pulse duration, as well as energy and wavelength, can be continuously varied. Full pulse energy is delivered at reduced peak power.

The LAI 101 PAL-PSTR Pulse Stretcher provides, quite literally, a new dimension in laser performance. Laser pulse duration, as well as pulse energy and wavelength, can now be continuously controlled. This permits laser peak power to be fixed as pulse energy is varied, or conversely, peak power to be varied at nearly constant pulse energy. Pulse duration can be continuously varied over the very important range from about 100 nsec to several microseconds. Using these stretched pulses, optical fiber energy damage thresholds are dramatically enhanced in both the PAL™ fundamental (720-800 nm) and second harmonic (360-400 nm) spectral regions. The fundamental wavelengths are well suited for studies of optical fiber transmission and loss, optical damage, nonlinear optical processes, and for medical research and applications including lithotripsy and laser tissue interactions. The shorter, UV wavelengths are of potential importance in photolithography, photochemistry, and medical applications such as dentistry, angioplasty, and general surgery. The LAI 101 PAL-PSTR provides a fiber optic deliverable near UV source with an average power approaching 0.5 watts.

The highest intensity solid-state source of tunable UV lasers. Replaces excimer lasers, UV ion lasers, and dye lasers for photochemistry, LIDAR, photolithography, Fiber Bragg Gratings, UV interferometry, and other applications of scientific lasers.

The Light Age family of nonlinear optical frequency generators exploits the full capabilities of recently developed materials to achieve exceptional conversion efficiencies. The LAI 101 PAL-SHG Second Harmonic Generator delivers up to 200 mJ of tunable UV (360-400 nm) radiation at a repetition rate of 20 Hz when used alone with a LAI 101 PAL™ laser. The addition of a LAI 101 PAL-THG produces up to 50 mJ of light tunable over the deep UV (240-267 nm) including 248 nm UV lasers and in the fourth harmonic 193 nm UV lasers. The THG contains a proprietary polarization conditioning element (patent pending) and operates in concert with the SHG to yield close to a watt of deep UV laser radiation. Custom crystals and coatings are available for doubling Raman shifted output at other wavelengths.
