Our laser module portfolio encompasses advanced photonic technologies tailored for high-precision industrial and scientific applications. Diode-Pumped Solid-State (DPSS) lasers utilize semiconductor laser diodes to optically pump solid-state gain media such as Nd and Nd₄. These systems achieve high beam quality and enable access to wavelengths like 532 nm through frequency doubling with nonlinear crystals such as KTP. Single Frequency Diode Lasers, employing techniques like Distributed Feedback (DFB), Distributed Bragg Reflector (DBR), and External Cavity Diode Lasers (ECDL), offer narrow spectral linewidths in the kilohertz to megahertz range, essential for high-resolution spectroscopy, coherent optical communications, and atomic physics experiments.

Our Tunable Lasers provide precise wavelength adjustability via mechanical tuning with diffraction gratings, electro-optic tuning by altering refractive indices, or temperature tuning of the gain medium. Q-Switched Lasers, featuring active modulation using acousto-optic or electro-optic modulators and passive modulation with saturable absorbers like Cr, generate high-intensity pulses in the nanosecond to picosecond regime, suitable for laser machining and LIDAR applications. Pulsed Lasers, including mode-locked and gain-switched variants, deliver ultra-short pulses for time-resolved spectroscopy and nonlinear optics. Continuous Wave (CW) Lasers maintain stable output power, fundamental for applications such as optical trapping and interferometry. Modulated Lasers offer amplitude, frequency, or phase modulation using direct or external methods, indispensable in optical communication and signal processing.

In terms of output characteristics, our lasers feature Polarized Outputs achieved through Brewster windows, anisotropic gain media, or polarization-selective feedback, enhancing performance in polarization-sensitive systems. Circular Output Beam Lasers employ beam shaping optics and micro-optics integration to correct the typically elliptical beam profiles of laser diodes, facilitating precise focusing and coupling into symmetric optical systems. Line Generation Lasers utilize cylindrical lenses, diffractive optical elements, or Powell lenses to produce uniform intensity distributions along a line, integral in machine vision and structured light scanning.

Our modules are designed with various form factors and physical features, including Compact Lasers with integrated optics and efficient thermal management for space-constrained applications, Fiber Pigtailed Lasers with high-precision alignment and hermetic sealing for flexible beam delivery in fiber optic networks, and Separated Geometry & Laser Heads that decouple the laser cavity from control electronics for operation in harsh environments. Power and control features encompass Internal Power Supply Lasers with switch-mode power supplies and protection mechanisms, USB Powered & Controlled Lasers enabling standardized power and digital interfacing, and Microprocessor Controlled Lasers offering feedback control loops and advanced digital modulation schemes.

Environmental specifications are addressed with Thermoelectric Cooling Lasers utilizing the Peltier effect and closed-loop control systems for wavelength stabilization and improved lifespan. Extreme Environment Lasers are engineered with robust mechanical designs and radiation-hard components to withstand wide temperature ranges, shock, and vibration, essential for aerospace and military applications. Water Resistant Lasers with IP67 ratings feature sealed enclosures and corrosion-resistant materials for reliable operation in outdoor and marine environments.

These laser offerings represent state-of-the-art advancements in photonics, engineered to meet the stringent demands of professional and industrial sectors. By integrating cutting-edge technologies and robust design principles, they provide precise specifications, high reliability, and adaptability across diverse operational environments, supporting a wide array of applications from metals processing to advanced scientific research.
