Nanosecond Lasers

Travelling Wave Optical ParametricGenerators (TWOPG) are an excellent
choice for researchers who need
an ultra‑fast tunable coherent lightsource from UV to mid IR.

The units can be divided into several
functional modules:▶ optical parametric generator (OPG);▶ diffraction grating based linewidth

narrowing system (LNS);▶ optical parametric amplifier (OPA);▶ electronic control unit.

The purpose of the OPG module isto generate parametric superfluorescence (PS). Spectral properties of thePS are determined by the propertiesof a nonlinear crystal and usually varywith the generated wavelength.
In order to produce narrowband
radiation, the output from OPG isnarrowed by LNS down to 6 cm⁻¹and then used to seed OPA.
Output wavelength tuning isachieved by changing the angle ofthe nonlinear crystal(s) and grating.
To ensure exceptional wavelength
reproducibility, computerized control
unit driven precise stepper motors
rotate the nonlinear crystals anddiffraction grating. Nonlinear crystal
temperature stabilization ensureslong‑term stability of the output
radiation wavelength.
In order to protect nonlinear crystals
from damage, the pump pulse
energy is monitored by built-in
photodetectors, and the control unit
produces an alert signal when pumppulse energy exceeds the preset value.
For customer convenience thelaser can be operated from masterdevice or personal computer throughUSB (VCP, ASCII commands), RS232(ASCII commands) or LAN (REST API)
interfaces or from remote control padwith backlit display that is easy toread even while wearing laser safety
glasses.
