Compact Pulsed Nd:YAG Lasers

Del Mar Photonics offers compact pulse Nd:YAG lasers with excellent beam quality, high energy/efficiency and possibility of efficient PRR changes with no significant degradation of the output beam parameters. No matter how you may wish to use it — as a stand­alone laser or as a pump source for tunable lasers and OPO — the Del Mar Photonics LQ529 laser provides a combination of high operation parameters, reliability and reasonable price which could not be achieved earlier.

Ring cavity design of the LQ529 oscillator ensures perfect balance of energy, beam quality and reliability.

Excellent Beam Quality
Compensation of depolarization over the Nd:YAG rod cross­section together with traditional advantages of ring cavities ensure excellent beam profile. Unique optical design of the LQ529 not only makes losses and distortions caused by induced birefringence almost negligible, but also minimizes thermal lensing effect. The above allows the user to vary pulse repetition rate within a wide range and requires no further cavity alignment to preserve high beam quality and output energy.

LQ529 lasers provide smooth beam profile for all harmonics.
This constitutes a great advantage over lasers using expensive and difficult to align Gaussian optics and thus demanding realignment and sometimes even replacement of optical components in order to avoid dramatic worsening of their output parameters if pulse repetition rate (PRR) has been changed.
Energy Through Efficiency
One of the main reasons for moderate efficiency of conventional Q-switched lasers is birefringence induced in the Nd:YAG rod leading to depolarization of laser output. Each time the beam passes through the cavity, depolarized lasing is filtered by various polarization units and is dropped out of the cavity that leads to decrease in laser operation efficiency. Optical design of the LQ529 laser cavity allows to practically eliminate energy losses caused by depolarization and provides laser energy output with more than 2% wall-plug efficiency of a laser system (total electrical-to-optical power efficiency). Such a high efficiency allows the LQ529 to provide up to 600mJ output energy without using an amplifier. Single rod and single flash lamp design is the determining factor for reduction of the laser price and maintenance costs.
