In 1986, Hitoshi Inoue founded LIC Engineering (formerly Laser Innovations Corp.) in Sunnyvale, CA to manufacture and market Super Pulse & Ballastless CO2 laser power supply.  In the 1990s, LIC Engineering introduced its first flat-type water cooled CO2 laser power supply, the CSF-series.  In the mid ’90s, the company introduced cost effective 600W/1KW CPF-series and the highest power of 25KW CSF-25000PD & CSF-25000/8.  These CSF-& CPF series are the most popular and long run products among LIC Engineering’s products line. Since the company introduced the first water cooled power supply in the late ’80s, the company has continued to manufacture the high efficient soft switching and unique water cooled CO2, Yag, and Capacitor charging laser power supply.

LIC Engineering is also the pioneering company for the QCW LD-Drivers and Super Pulse for laser diode applications. In 2005, the company introduced the first high peak current, fast rise time and ultra high QCW power laser diode drivers.  LIC was one of the first companies to make the QCW laser diode power supplies and has since added a wide variety of High Power LD Driver, High Power QCW Laser Diode Power Supplies /Gas Discharge solutions.

High Speed/High Voltage/High Current Switching :
To achieve a high voltage/high current and high speed switching at the same time, LIC Engineering uses combinations of the MPC and advanced, high speed semiconductors.  With the circuit technologies accumulated in the past 35 years, LIC Engineering made it possible to switch a 5KA/15KV pulse within 8-15 nanoseconds.  LIC’s LSP series voltage ranges from 500V to 15KV, and currents ranges from 500A to 5KA.  Pulse rise time range from 100ps to 15ns with minimum pulse widths as low as 5 ns.

High Efficient Resonant Switching & LIC Super Pulse:
Since the first product was developed in early 1980s, LIC’s switch-mode CO2 laser power supply has used series resonant topology, which makes switching current “sinusoidal” or ”zero-current switching” minimizing switching loss while sourcing a very high current into the secondary circuit in very short time.  This zero-current switching technology makes LIC’s products highly efficient with some products exhibiting electrical efficiency over 98.6% with a 500W output power level.  The technology also makes it possible to generate very high peak pulse called Super Pulse, which was pioneered by LIC in the early 1980s for a surgical CO2 laser system.

LIC Engineering has been designing and building laser related power supplies and devices for over 30 years and this experience goes in to every product we build today.
