New All-Fiber Based Mendocino Laser Generates 50 mW Of 780 nm Ultrafast Pulses
Pulse width is < 0.1 ps and pulse energy is > 1nJ at 50 MHz, with average output power > 50 mW. An optional higher power output version, up to 500 mW, will be available soon.
The unique all-fiber design of Calmar's Mendocino 780 nm laser naturally provides excellent stability and reliability in harsh environments with years of hands-off use, essential for OEM applications.
Our 780 nm laser is a second harmonic generation (SHG) product of Calmar's passively mode-locked fiber laser in the C-band. Calmar's seed laser uses a proven semiconductor saturable absorber approach, which ensures consistent and reliable mode-locking. In contrast, some of our competitors use a nonlinear polarization rotation design, which is intrinsically sensitive to temperature, time, and other external disturbances, resulting in inconsistent operation at start-up and intensive operator attention. In contrast, Calmar's lasers provide simple, consistent, hands-off operation.
Calmar's unique all-fiber design also allows our laser to be many times smaller than most other solid state or fiber lasers with free space elements. Calmar's 10 mW 780 mW laser is only 19.7 x 12.7 x 7.0 cm3 and runs from a 5 V supply. The 50 mW 780 nm fiber laser head is 15.2 x 12.7 x 6.0 cm3, and requires a driver supply at 34.0 x 30.0 x 9.0 cm3. (Smaller driver units are possible on request.) The Mendocino laser is also available in a bench top or rack mount configuration for laboratory use.
Fiber optic technology enables Calmar Laser to produce highly reliable compact lasers with short pulse width, high peak power, and excellent beam qualities. The steady laser pulse output characteristics are actually determined by soliton effects of fiber laser cavity. Since fiber gain, dispersion and nonlinear effects are very stable over time, temperature, and other external disturbances, our seed laser output is very stable.
Fiber lasers have a gain medium based on a doped optical fiber pumped by an efficient and reliable telecom qualified semiconductor laser. Splice fused fiber optic connections provide robust long term stability, and long thin fibers allow simple passive cooling methods. Calmar's fiber laser components have been engineered to pass very stringent industrial standards. All these properties fundamentally give Calmar's fiber lasers advantages in terms of high reliability, high efficiency, and compactness.
