Linear PDM for femtosecond pulse shaping

OKO introduces 20-ch linear piezoelectric deformable mirror for femtosecond pulse shaping. The mirror has 10x50mm active area, controlled by two rows of 10 actuators each. Actuator pitch is 5 mm. Maximum surface deflection is 8 um, figure difference between adjacent actuators can reach 3um. The initial figure is slightly spherical. The mirror can be custom coated with dielectrics and metal-dielectrics. Short (4.1MB) interferometric video of the moving mirror surface. The mirror can be supplied with a complete set of control electronics, including 20-ch 400 V amplifier unit and a 20 (40)-ch USB DAC unit (or a 24-ch 8-bit PCI DAC card) for interfacing to a PC.

Driver for high-power laser diodes

OKO technologies offers a new line of driver electronics for high-power laser diodes. These drivers were developed and manufactured in Russia. They offer exceptional versatility, precision and stability for a very reasonable price.

High-voltage amplifier unit

OKO introduces 20(40)-ch high-voltage amplifier units for membrane and piezoelectric deformable mirrors. Features small (40x200x280mm) size, active cooling, low (20W) energy consumption and wide range of AC power supply voltages (85 to 250V). Full signal 400V response is linear from DC to 1kHz on a loads of up to 15nF. Unlimited number of units can be combined to drive deformable mirrors with more than 40 channels.

PDM for high-power lasers

OKO Technologies introduces 50mm 37ch athermal piezoelectric deformable mirror for high-power laser applications. The mirror features 8000 nm full stroke, 2200 nm inter-actuator stroke. The mirror is specially designed to operate at complex load and temperature conditions.
