Technologies

Q-Peak manufactures diode-pumped, solid state lasers based on a number of standard, field-proven components that can be arranged to provide a wide variety of operating configurations. Our current products are based on over 20 years of innovative efforts in developing laser systems. For more details, and some background on the evolution of our current product line.

Our systems are designed to produce cw and pulsed average powers of 10 W and above in the near-infrared (IR) wavelength region (around 1000 nm) with a near-diffraction-limited beam quality. Outputs in the green and ultraviolet (UV) regions are available, at present only in a pulsed format.
Our core technology is based on a diode-pumped Gain Module developed to operate with a number of different solid state laser materials. With the Gain Module technology and appropriate laser resonator optics mounted in a laser head, we can generate cw or repetitively Q-switched, pulsed laser-output formats. In addition, the Gain Modules can be used amplify the cw or Q-switched outputs of Gain-Module oscillators, or amplify other sources, such as low-power mode-locked lasers or sub-nanosecond, Q-switched microchip lasers. We can also provide standard nonlinear optics components for harmonic generation into the visible and UV wavelength regions.

Solid-State Lasers

Q-Peak has been involved in solid-state lasers since 1985 during the time when the pumping mechanism for solid-state lasers transitioned from flash-lamps to diode lasers. Lasers based on flash-lamp pumped Neodymium-, Erbium-, Thulium-, and Holmium-doped laser materials (the Laser 1-2-3) was Q-Peak’s first product. Another early product line was based on Titanium-doped sapphire and included a cw, tunable, single-frequency laser (the Titan cw); a tunable, pulsed, Ti-sapphire laser (the Titan P); and a mode-locked Ti-sapphire laser (the Titan ML).

Fiber Lasers

Q-Peak fiber lasers deliver unique optical performance. Q-Peak is a world pioneer in high power fiber lasers and fiber amplifiers. Q-Peak has been developing high-power, Tm:silica fiber lasers since 2006 and routinely constructs 100s of Watts average power, 2-µm fiber laser systems with 60% optical-optical efficiency. For over a decade, we have constructed all types of high power fiber lasers and fiber amplifiers at 1-µm, 1.55-µm, and 2-µm using innovative technologies and the most advanced optical fiber processing equipment.

Ultrafast Lasers

Q-Peak offers ultrafast lasers utilizing novel gain materials for use in scientific research and materials processing applications. Our capabilities include ultrafast, high-repetition rate oscillators, pulse stretcher and compressors, and an array of regenerative and linear amplifier systems for the generation of high-peak powers. The output from these laser systems can be combined with our non-linear optics capabilities providing wavelength tunabiltiy from the UV to IR. These individual components can be combined to provide a custom laser system to meet your needs.

Nonlinear Optics

Q-Peak expands the wavelength capability of our solid-state and fiber lasers by developing and constructing wavelength conversion modules based on nonlinear optical techniques. They include harmonic and parametric generators, parametric oscillators and amplifiers, and sum frequency generation (SFG). Typically, second-, third-, and fourth-harmonic generators (SHG, THG, and FHG, respectively) shift the fundamental laser wavelength to shorter, discrete wavelengths, whereas the parametric conversion allows for covering longer wavelengths and broad-band tuning.
