Laser Diodes

Knight Optical We can offer Custom Moulded Aspheric Lenses for use with Laser Diode Collimators. Aspheric lens surfaces are used to correct spherical aberration (where the converging light from a lens does not have a common focal point, resulting in a distorted image) in lasers and imaging. Traditional spherical lenses cannot collimate light effectively because even small angles of incidence can produce spherical aberrations. This can mean that several components may be required to get the desired result. The non-spherical surface of an aspheric lens allows a single component to effectively focus or collimate even highly divergent emissions, potentially replacing a multi-lens system with a single aspheric lens. Therefore Aspheric Lenses that are moulded are ideal for use within laser diode-to-fibre coupling applications. For more information read PDF ….

LAS 5000XD uses Tunable Diode Laser Spectroscopy (TDLS) and comes in various models for measuring parameters such as NH3 + H2O, HF, CO + CO2, O2, HCl + H2O, etc. It combines robustness, fast response time (1 s) and high accuracy measurement in harsh environments.

Ceramic reflectors supplied by us work particularly well in Ruby and Nd:YAG laser pumping chambers and can be a highly cost effective alternative to metal coated reflectors. They are also used extensively as reflectors in housings for high intensity lamps. > resists chemical attack > has high strength > has a high reflectivity over a broad wavelength band > has good thermal conductivity and > excellent dimensional and electrical stability at all operating temperatures.

The CryLaS Q-series lasers are diode-pumped solid-state lasers (DPSS lasers) based on a microchip design. It consists of a Nd:YAG resonator with a directly coupled saturable absorber that works as a passive Q-switch. The compact housing and simple operation make the lasers an ideal light source for applications that require minimal housing dimensions with maximum performance. Based on the 1064 nm fundamental, non-linear optics (NLO optics) generate frequency multiples of this fundamental, covering a broad spectrum of laser wavelengths from 1064 nm to 213 nm. The FDSS532-Q1 laser emits pulses with a pulse width of approx. 1 ns at 532 nm and can be modulated from single shot to 20 kHz. The pulse energy is 2 µJ. CryLaS lasers impress with their simple installation, service-free operation and long service life.
